Question

which one of the following give A+B =pi/4. a belongs to (0,pi/2) and b belong to (0,pi/2)

Answer 1

The function `f(x) = {x+asqrt2 sinx, 0<=x<=pi/4 and 2x cotx+b, pi/4<=x<=pi/2 and a cos 2x-bsinx, pi/2,x<=pi` is continuous for `0<= x <=pi` ,then value ...

Answer 2

Answer:

f:[0,4π]→[0,π],f(x)=cos

−1

(cosx)

⇒ point A, B, C satisfy f(x)=

10

10−x

Hence, 3 points
