Find the tangent to the curve y=x^3+3 at the point x=1.

1. Differentiate the Equation of the curve to find the gradient: y'=3x^2 2. The gradient of the tangent is found by substituting x=1 into y'=3x^2: Gradient of tangent=3 3. Now we must find out the co-ordinat...

Use the substition u = cos(x) to find the indefinite integral of -12sin(x)cos^3(x) dx

We are given the substitution to use, so the first step is to differentiate "u" with respect to x . du/dx = -sin(x) Now, to replace the "dx" in the original integrand with something in te...

Differentiate x^3(sinx) with respect to x

As we are differentiating a product (two things times together) we can use the product rule which is if: y = u(x)v(x) then dy/dx = u(dv/dx) + v(du/dx). So firstly looking at our equation we need to identify ...
