Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int {\cos (ax + b)dx = \frac{1}{a}} ...

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse, as ...

THE Paralogistes pseudomathematicus has become so rare, or possibly so shy, that it is a real pleasure to find that the species is not extinct. Alack! that De Morgan is not with us, to do justice to ...

Remember that integration is the inverse procedure to differentiation. So, if you can do trigonometric differentiation, you can do trig integration.

For some very simple circuit, a two-pole RC lowpass filter in this case, we can very easily derive the algebraic transfer function and look at the circuit’s gain and phase properties. An examination ...
