Good Morning Sir 1:02:18 Sir dont you think that the question should tan-1 63/16 = sin-1 5/13 +cos-1 3/5 bcz the values are not matching in the question you had given
1:02:03 Hey everyone, in this question sir has mistakenly shown "+" instead of "-" between tan inverse and sin inverse. Kindly use the correct sign to solve the question :D (ur welcome)
Thanku so much bro Maine sare formulas yaad kar liye the , fir jab sir ne apply Kiya mujhe kuchh smj hi nhi aaya Your comment helped me a lot Thanks again 😊

24:24 Question is →cos-1(1/2)+2sin^-1(1/2)

→π/3 + 2π/6

prove that sin^-1(5/13)+cos^-1(3/5)=tan^-1(63/16)

@nikhilesharun1026 thanks bhai
1:02:13 sir question is wrong
The correct question is tan-¹63/16 = sin-¹5/13 + cos-¹3/5 !
According to miscellaneous exercise ques no. 7
Yes sir this question is wrong
My answer is not matched please sor😢
Hlw bhaiii
Question sign wrong
1:30:25 root1by3

haa
Tan-1 63/16 - sin-1 5/13 =cos-1 3/5 correct question . solve this and you will get the correct result

Btw at 1:39:25 0
1:40:05 sir this is wrong cos decreasing function hoga isliye inequality reverse ho jaayegi waise [0,1] aaiga
H bhai
in the question at 1:40:01 cos^-1 is a decreasing function so sign of inequality will change while shifting it
46:51 answer== -π
-π/3
-π/3 correct answer
-pi/3 correct answer hai
i think tumne radian ka value likhne mai galat kar diya tan ya fir cot ka
Bhai wo π/3-π+π/3 ho gaa naa kee π/3-π-π/3
Bhai lekin cot-1 ki range to[ 0,π ]hai
1:39:28 as cos is a decreasing function while using it, the inequality will change.

Cos is an invertible funtion so the signs will change and it will become cos(0) >= 2x-1 >= cos(pi) so the answer will be 1 >= x >= 0
