Answer:
1.Evaluate the limit as x approaches 0 of (sin(x))/(x):
Using L'Hopital's rule, we can take the limit of the derivative of numerator and
denominator. The derivative of sin(x) is cos(x) and the derivative of x is 1. So the
limit becomes:
lim(x->0) (sin(x))/(x) = lim(x->0) (cos(x))/1 = cos(0) = 1
2.Find the derivative of y = x^2:
The derivative of y = x^2 is dy/dx = 2x
3.Evaluate the definite integral of x^2 from x=0 to x=1:
The antiderivative of x^2 is (x^3)/3. So the definite integral is:
(x^3)/3 from 0 to 1 = (1^3)/3 - (0^3)/3 = (1/3) - 0 = 1/3
4.Find the second derivative of y = cos(x):
