Cos4x 1 cotx tanx

The denominator contains tan and cot functions. They have to be changed to another form to simplify the expression. The quotient trigonometric identities are useful to express tan and cot function in terms of sine and cosine functions. The subtraction of square of sin of angle from square of cosine of angle represents cos double angle identity. The numerator can be simplified by applying sum of one and cos of double angle trigonometric identity. In order to use this rule, a small mathematical adjustment should be made firstly. The trigonometric expression is successfully simplified and the integration of the function can be performed immediately. The integration of sine function can be performed by the integral of sin function formula. This formula can be used directly due to different angle and element of integration. So, use replacement technique to make the integration of the function possible.

Wiki User. So as long as you have two sides of a right triangle, then you can find the angles and the length of the third side. So: for this point, both angles are 45, and the distance to x cos is equal to the distance to y sin. Because it tends to infinity. Additionally, tangent can be expressed as sin theta divided by cos theta. The sine of 90 is 1. The cosine of 90 is 0. That would be 1 divided by 0, or division by zero; which is undefined.
