TRIG FUNCTIONS

 

SINE, COSINE, and TANGENT can be displayed on the same chart. Use a spreadsheet to display over the range -90<q<90.

 

Sine and cosine functions have a maximum value of 1. Tangent has a maximum value of infinity. In order to display a readable chart we need to distort the sine and cosine by multiplying by 60 and leaving out some values for the tangent. Remember, a chart can distort or mislead by not including all information.
