The cotangent of an angle is the reciprocal of the tangent. Recall that the tangent is defined as the opposite side of a right triangle over the adjacent side. Also, a reciprocal function is equal to 1 over the original function. This means that the cotangent is equal...

The cosecant of an angle is defined with respect to the sides of a right triangle. In a right triangle, the cosecant is equal to the length of the hypotenuse divided by the side opposite the angle. The cosecant is the reciprocal function of the sine. Here, we will...

The secant of an angle can be calculated by relating the sides of a right triangle. The secant is defined as the reciprocal function of the cosine, so it is equal to the length of the hypotenuse over the length of the adjacent side. The secant of the most important...

Revolutions are a way of measuring complete turns in circles. Revolutions are used in various situations where an object makes a large number of turns and it is more convenient to measure the number of turns the object makes per minute or per second. For example,...

Radians are a way of measuring angles. Radians are mainly used when we want to perform advanced mathematical operations such as differential or integral calculus. This is because the radian has a relationship to the radius of the circle. On the other hand, revolutions...
