Q. 16

# Evaluate the foll Since cosec x = 1/ sinx Multiply with (1 + sinx) both numerator and denominator Since (a + b) × (a - b) = a2 - b2,  Let sinx = t

dt = cosx dx

therefore, multiply and divide by 2 and add and subtract (1/2)2 in denominator, Let t + 1/2 = u

dt = du Since,    Rate this question :
