The six trigonometric ratios are: Sine: (sin) Cosine: (cos) Tangent: (tan) Cotangent: (cot) Cosecant: (cosec) Secant: (sec) 😅😅😅 😅 Trigonometric ratios relate the ratio of sides of a right triangle to the respective angle. They are expressed in terms of a right-angled triangle, and their values are determined using properties of triangles. The standard angles for these trigonometric ratios are 0°, 30°, 45°, 60°, and 90°. These angles can also be represented in the form of radians such as 0, π/6, π/4, π/3, and π/2. One way to remember the trigonometric ratios is to use the acronym SOH-CAH-TOA: SOH: Sine is opposite over hypotenuse CAH: Cosine is adjacent over hypotenuse TOA: Tangent is opposite over adjacent
2:07:07 sir 👨🏫 agar iss wale question❓me R.H.S. se solve ↙️ kre to Sin²A/1-cosA ->1-cos²A/1-cosA. 🔥 ->(1-cosA)(1+cosA)/1-cosA. ☑️ 👽 (Identity use ki hai a²-b² wali kyuki 1 ka square 1hi hota hai)👽 ->now ✨ (1-cosA)(1+cosA)/1-cosA isme 1-cosA kat jaenge...🍷 -> 1+cosA ->1+1/secA ->secA+1/secA (L.C.M. liya hai )🤡 L.H.S Hence proved....❤👍🎯
You can see the denominator in RHS: is 1-CosA. So in Lhs he multipled the denominator with 1-CosA. Aur agar denominator me multiply Kiya ho to uper bhi krna he pdega ye rule h.
59:43 Question 11 (v) :- False Because Given, sin = P/H= 4/3 P=4k H=3k 4k>3k Here Perpendicular(P) is longer than Hypotenuse(H) But H should always be longer than P Hence false
29:55 itna krne ke alawa ek right angled triangle leke and cosA=cosB krne ke AC/AB=BC/AB mei AB dono side cancel out krke AC=BC keh skte the, aur angle A=angle B hojata kyuki angle opposite to equal sides are equal
31:27 sir ye vala question simply ek right angle triangle bna ke ni ho sakta kya jisme angleA or angleB acute angle honge usse to bhut simple ho jata question😅
Sir NCERT ke questions ke sath concept bhi kara dete atleast in upcoming lectures then it would be really help full for basic student's as upar koi dhyan nhi de raha😭
1-2+2cos hai isme jo 2cos hai vo multiply me hai is tarah 2xcos =2cos. to isme jo pehele -2 hai vo minus nahi hoga vo ( 1-2+(2cos) is tarah hai Aap shayad shayad jo -2 hai usko 2cos ke sath minus kar rahi de rahi hongi ! samajh aya ?

1:00:05 answer :- False
Because Sin theta = P/H
and H is the longest side....
but here H is small ..so this is false

Vote for ritika sir to see in class 11😅
Most of the students are watching this the day before the exam😅
The six trigonometric ratios are:
Sine: (sin)
Cosine: (cos)
Tangent: (tan)
Cotangent: (cot)
Cosecant: (cosec)
Secant: (sec)
😅😅😅
😅
Trigonometric ratios relate the ratio of sides of a right triangle to the respective angle. They are expressed in terms of a right-angled triangle, and their values are determined using properties of triangles.
The standard angles for these trigonometric ratios are 0°, 30°, 45°, 60°, and 90°. These angles can also be represented in the form of radians such as 0, π/6, π/4, π/3, and π/2.
One way to remember the trigonometric ratios is to use the acronym SOH-CAH-TOA:
SOH: Sine is opposite over hypotenuse
CAH: Cosine is adjacent over hypotenuse
TOA: Tangent is opposite over adjacent
Vote for ritik sir in class 11 1k like target for ritik sir❤❤
2:08:09 how ??????? is that allowed
Rationalise kar sakte ha wo allowed ha
R:H:S
Using identity
Sin^2A=1-cos^2A
1-cos^2A/1-cosA
Using identity
A^2-B^2=(A-B)(A+B)
(1-cosA)(1+cosA)/1-cosA
1+cosA
L:H:S
Hence proved

1:00:08 False because hypotenuse is always grater than base and perpendicular
1:11:33 sir ans ko rationalize bhi toh karna hoga?
1:11:24 sir galat answer hai
Ncert ma 3√2-√6/8 hai
Abe gadhe dimag se paidal hai kya sir ne bola to ki rationalise kar lena
2:08:17 can anyone explain this added part
You can see the denominator in RHS: is 1-CosA. So in Lhs he multipled the denominator with 1-CosA. Aur agar denominator me multiply Kiya ho to uper bhi krna he pdega ye rule h.
Kon kon pre-board ki tayari kr rha hai 😊
False, because sin=P÷H and hypo is longest side of triangle
59:43
Question 11 (v) :- False
Because
Given, sin = P/H= 4/3
P=4k
H=3k
4k>3k
Here Perpendicular(P) is longer than Hypotenuse(H)
But H should always be longer than P
Hence false
1:00:12 false because perpendicular can't be greater than hypotenuse
1:00:06- False as the hypotenuse is bigger than the perpendicular but hypotenuse is the longest side of a right triangle.
29:55 itna krne ke alawa ek right angled triangle leke and cosA=cosB krne ke AC/AB=BC/AB mei AB dono side cancel out krke
AC=BC keh skte the, aur angle A=angle B hojata kyuki angle opposite to equal sides are equal
No bro you re wrong
Yeah it's also correct
Yes 💯 correct my teacher also told me this
Yesss it is ✅✅✅✅✅✅✅ 😊
Yessss
31:27 sir ye vala question simply ek right angle triangle bna ke ni ho sakta kya jisme angleA or angleB acute angle honge usse to bhut simple ho jata question😅
Ha wahi to itna hard bana diya ..Maine phir dusre channel me ja ke dekha to usne 2 min me kardiya
Ha
1:00:05 false because hypo

BC jab main class 10 main tha tb trigonometry mujhe bilkul samjh nhi ata tha ab main 12 main tb mujhe ye trigonometry halwa lgta ha 😂
1:00:08 False because perpendicular is 4 and hypotenuse is 3 which is not possible. Hypotenuse is always greater than base and perpendicular.

kya nahi samajh aya bhai?

1-2+2cos hai isme jo 2cos hai vo multiply me hai is tarah 2xcos =2cos. to isme jo pehele -2 hai vo minus nahi hoga vo ( 1-2+(2cos) is tarah hai Aap shayad shayad jo -2 hai usko 2cos ke sath minus kar rahi de rahi hongi ! samajh aya ?
Nhi !! Sorry pr Mai ye nhi pucch rahi hu ye 1-2+2cos² hi kaise aaya
