Two straight lines can intersect at only one point. To identify the point at which the lines cross, we make a simultaneous equation, and solve x and y from here, by firstly writing one equation on top of ...
When we integrate by parts, we begin by setting the first term to equal some variable U, the second term in the integral we set to be dv/dx. Then we differentiate the U to obtain du/dx and integrate dv/dx...
tanx = 4cotx + 3 - Multiply through by tan to form a quadratic. tan^2x = 4 + 3tanx - Simplify by allowing y to equal tanx. y^2 = 4 + 3y - Rearange to standard quadratic form. y^2 - 3y -4 = 0 - Factorise....
First we follow the "times by the power and take one from the power" rule. This is the easiest way to remember how to differentiate anything.
So (3x4)x(4-1) -(2x2)x(2-1)<...
The integration by parts formula: S:udv/dx = uv - S:v*du/dx, where S: means "Integral of with respect to x"
Let 2*x be u and sin(x) be dv/dx
So du/dx =2 and v= -cos(x)
