Question

Find derivative of :- dy/dx

1. Y=3x-²+4x³+5x+7

2. Y=2x²+7x-³+4x+3

3. Y= (2x+1) (3x+5)

4. Y=(x³-4x+2) (x-1)

Find integration of :-

1. In limit of 0-1 ,, (2x²+3x+5) dx

2. In limit of 0-1,,, (3x-²+5x-³+4x+7) dx

3. In limit of 1-2,, (2x+3) (3x²-1) dx

4. In limit of 0-π,, (sin x + cos x)

Answer 1

Explanation:

(1)--> dy/dx=d(3x-²+4x3+5x+7)/dx

using addition rule

dy/dx=-6x-³+12x²+5

(2)--->dy/dx
