Now please teach me how to break down the number that quickly

i did it more faster😂

Isne class 10th me advance maths liya hoga

Both are wrong

Easy peasy just divide the number to 360º😁

Do 1841° 😅

Jee aspirants can do this orally

Ye 10 mai kab aaya 😂

Glt hai possible nhi hai

Explain this in short

Simple formula is. Sin 1845 =.( 1800+45 ) = Sin 45°=1/√2

1800 elminate karo aur Sin120 Sin45 ka man nikal lo

Bhai sin 1920 is wrong answer

Let me do more easy than if a number is multiplied by 360 will always be 0 so the next number will be your answer like (1800+45) so 1800 becomes 0 and you will get 45 Thank me later 😎😎

In sin1845 Kych nahi karna 1845/180 180*10 =1800 1845-1800=45 Sin45 = 1/√2

Thanks sir 👍

90 ka table use ok dear sir

Why 90°? 360° will make life easier.

Good 👍

2nd question is rong because last me cos 45 hona chahiye ,,, likin answer is same

Sbbb bakchodi hai....aajtak kahi use nhi aya life me ye sbb

Class 11th third chapter trigonometric function . Sin1920=sin(5×360+120)= sin(120) =-√3/2. Sin1845=sin(5×360+45)=sin45=1/√2

What Is the importance of trigonometry in our life

Solved it without pen paper lol

Prime factorisation krke solve krne ka kya zarurat hai! Direct 360 ghuma ke quadrant check krke answer do na!🤦🏻

Bina pen wale ques hai ye

Bhai pagal ho kya itni trigo lga k champion bn gye trigo in sbse bhut aage h mere bhai..but effort acha h aapka..

Op BROTHER

Sin1920° = √3/2 Sin45° = 1/√2

In wbbse this type of questions are not allowed

Bro sin1845 is wrong answer is root2/2

Samajh mein nahi aya

You don't need to write it, just calculate in mind. 😂😂😂😂😂

Sin 1845* ka ans -1/root 2 hoga na

Math lover thoko like❤

Legend: Calculator 😂

Calculator left the chat😂😂😂

Studied in class 9

These students will excel in JEE ADV Only if its calculation based 😂😂

yesterday i stutied this topic in my school i did't even study nor i searched anything realted to it how can youtube recommend this me howww???

Power of Ratta 😂

tbh you don't need pen and paper

Nice

Bhai sin 1845 ko direct sin(10pi+pi/4) kar sakthe he and in that sense its sin(pi/4) which is 1/root2

Sin(2πn+Q)=sinQ ,where isQ=1,2,3,4 ..,now sin(2π×5+45)=sin45 so 1/√2

Not proper steps
