Question

If y=sintheta then dy/dtheta where theta= Pi/2

Answer 1

Answer:

the answer is '0'.

Explanation:

because,

              y=sinΘ           (where Θ=π/2)

               diffw.r.t 'Θ'

              dy/dx=cosΘ

             ( substituting Θ=π/2,we will get cos 90° )

                ∵ cos 90°= 0

∴ The answer is '0'.
