What is -cos(pi/6)?Finding the Values of Trigonometric Functions:We must remember the trigonometric function values of special angles to write that value directly in the solution. If the trigonometric function i
The period of any function is the value of the domain variable after which the function repeats. We have a cosine function given and we have to find the value of the period, we will do it as done in the solution. Periodicity of Trigonometric Functions:...

For the calculator to compute functions like exp, log and cos to within 10 digits with reasonable efficiency, it needs a few extra digits to work with. It is not hard to find a simple rational expression that approximates log with an error of 500 units in the last place. Thus computing...
