The explanation for domain and range of sin, cos, tan is very good. But I can't find other video for which explains about domain and range of cot, cosec and sec.
It's pretty easy once you understand this. Just use the reciprocating property. Like how they expressed tan in terms of sin and cos, express cosec in terms of sin, sec in terms of cos, and cot in terms of sin and cos

Dear mam, I feel like that you tell only the points in video without depth. It is irritating because I do not understand the reason behind what you say and nor does my books explains it. Please do not be obsessed to make your videos short. Please make it long with enough depth. Thankyou

Because tanx = sinx/cosx. The condition is when tanx is max, so sin and cos also should be max. sinx is max when it's value is 1 and cos is max when it's value is 0. tanx = sinx/cosx tan x = 1/0 tanx = ∞ (max) So, this same goes with negative infinity.
@@miraclin11 that's not the point. At 5:30 Range of tangent function is given as [-infinity , +infinity] You cannot include infinity in any closed interval. The correct Range will be (-infinity , +infinity) If domain is set of all *R*-{(2n+1)π/2: nε*Ζ*} Then surely, infinity cannot be included in the first place. Basically, Range of Tangent function is an open interval from negative infinity to positive infinity. As little nitpick it is, it will confuse people who will encounter this for the first time. Same happened with me when I had commented this 2 months ago. Now I'm much better.
You may notice that when the number in denominator is smaller than the numerator then the result tends to be greater so when the denominator is almost equal to 0 the result tends to be infinity.This is not applicable in mathematics this can be considered to be true when studying physics.
One may not define 1/0 as infinity, the value is undefined. One can use the principle of limits to prove that the operation of 1/0 is undefined since the value can be proved ambiguous by using the rational function f(x)=1/x. “Don’t memorise,” please correct your explanation.

Completely agree.
Yes please
Yes
I just Hit 100th like of your comment..
Yes plz
Part 2 never came 😢
Highly recommended.
Explained in very easy way..
The explanation for domain and range of sin, cos, tan is very good. But I can't find other video for which explains about domain and range of cot, cosec and sec.
It's pretty easy once you understand this. Just use the reciprocating property. Like how they expressed tan in terms of sin and cos, express cosec in terms of sin, sec in terms of cos, and cot in terms of sin and cos
Take reciprocal for cosec & sec.
To find tan,use tan x= sinx/cosx
Part 2????
Very well explained.. Thanks for such a great explanation mam......
Extremely easy to understand and helped me avoid my procrastination. Thank you so much ma'am
Ur teaches in an unquie way..
Thats the most beautiful part of education..🔥🔥

Thank you !!! Made everything much more clear...
thanks for making it easier. i really needed solidify this concept😍😍😍
Thank you so much for this mind-blowing explanation. You made it so clear that even a child can understand it.
Thank you once again.
Great explanation !
Thank you!!!
Thankyou so very much 💗
I don't understand how we put this idea to define domain and range of secant x, cosecant x and cotangent x?????
Can u plz explain 🥺
Super mindblowing
Part 2 plz...🙏🙏🙏🙏
Very well explained, thank you!
Good explanation thanks a lot
there are many part 1 videos related to trigonometry so it is difficult to find the appropriate one.but the teaching is very nice.
Right
See topics from NCERT maths textbook
Same here
@Hamza Shaikh why
@Hamza Shaikh everyone is free in corona period
Allhamdulilah I understand 🥰

Can we write range of tan function in closed interval?
Got my final math exam tommorow and this was hugee help mam.. Thank you 🙏

Amazing Ma'am
Nice teaching. So easy to understand 🥰
S theta appears in denominator for sin =1/cosec
Love it
Thaaaank you so much

Very nice ... I am not able to find the second part of the topic. Please provide the link
Had u post lymph topic of class 10
please send me Domain and range of trigonometry functions part 2
Probably this is the one of the longest video of don't memorise 😅😋
Short video but best video
3:21 in the domain of tanθ we can't put ZERO though it is a Real Number R IS THIS CORRECT ?
@@ashkechum502why my comment is wrong
@@youtubemedia4601 sorry your comment is correct
But there is exception that all real values except(2n+1)π/2, so it's correct
thanks
Upper limit of theta means ??? Plzz help
I dint understood how you wrote 2n+1
Why ? Please tell me reply..
Because cos thi tha value will be zero at odd multiples of 90 , and we have to eliminate such values of tan thi tha where cos thitha is zero ...
Give example please
Range of tantheta can be written As belongs to R
Nice👍

Thnq u ma'am for d kind reply
How is infinity included in the range of tan x?
Because tanx = sinx/cosx.
The condition is when tanx is max, so sin and cos also should be max.
sinx is max when it's value is 1 and cos is max when it's value is 0.
tanx = sinx/cosx
tan x = 1/0
tanx = ∞ (max)
So, this same goes with negative infinity.
@@miraclin11 that's not the point. At 5:30 Range of tangent function is given as [-infinity , +infinity]
You cannot include infinity in any closed interval.
The correct Range will be (-infinity , +infinity)
If domain is set of all
*R*-{(2n+1)π/2: nε*Ζ*}
Then surely, infinity cannot be included in the first place.
Basically, Range of Tangent function is an open interval from negative infinity to positive infinity.
As little nitpick it is, it will confuse people who will encounter this for the first time. Same happened with me when I had commented this 2 months ago. Now I'm much better.

mam can u please do part2
I don’t get how tan x = sin/cos = 1/0 is equal to infinity and not undefined. Shouldn’t it be limiting rather than infinity since 1/0 is not REAL!?!?
You may notice that when the number in denominator is smaller than the numerator then the result tends to be greater so when the denominator is almost equal to 0 the result tends to be infinity.This is not applicable in mathematics this can be considered to be true when studying physics.
How can 1/0 be infinity actually it is undefined
Wao man 😂 kbhi. Khud prh lia hota to ptaa hota😮
i can be wrong somewhere but how could you explain please?
@@ABC-ph5bq Go to 1883 bruh
@@Faiz_vlogs09 i am not understanding ur point
1/2 will mean 2 parts of 1 0.5 and 0.5 but 1/0 will mean infinite parts of 1 you get my point
Can someone please give me the link of part 2? please...
Nice
Thank you for your kind words, Prakash. Happy learning!😊
One may not define 1/0 as infinity, the value is undefined. One can use the principle of limits to prove that the operation of 1/0 is undefined since the value can be proved ambiguous by using the rational function f(x)=1/x.
“Don’t memorise,” please correct your explanation.
Any number over 0 is undefined but it must be either positive infinity or negative infinity and that depends on the sign of the numerator :)
Is part 2 release??
What is the range of cos^4x explain pls
How can we find inverse values of sin -1 and tan -1?
Where is the 2nd part🧐
This is very useful mam
can somebody please explain to me how 1/0 and -1/0 is infinity and -infinity?? shouldnt it be undefined????
infinity itself is undefined

But how can you include infinity in range of tan
when cosx tends towards zero the tanx tends towards infinity,
