`Assertion` Consider the following statements in `SandR`
`S:` Both `sinx and cosx` are decreasing function in the interval `(pi/2,pi) ` `Reason` If a differentiable function decreases in an interval `(a,b)`, then its derivative also decrease in `(a,b)`.Which of the following it true? (a) Both S and R are wrong. (b) Both `S and R` are correct, but R is not the correct explanation of S. (c) S is correct and R is the correct explanation for S. (d) S is correct and R is wrong.
