Answer» Find the derivative of the following functions at the indicated points : $(i) s i n x at x = \frac{π}{2}$ $(i i) x at x = 1$ $(i i i) 2 c o s x at x = \frac{π}{2}$ $(i v) s i n 2 x at x = \frac{π}{2}$

Find the derivative of the following functions at the indicated points : (i) sin x at x=π2 (ii) x at x=1 (iii) 2 cos x at x=π2 (iv) sin 2x at x=π2

Answer»

Find the derivative of the following functions at the indicated points :

$(i) s i n x at x = \frac{π}{2}$

$(i i) x at x = 1$

$(i i i) 2 c o s x at x = \frac{π}{2}$

$(i v) s i n 2 x at x = \frac{π}{2}$
