### Trigo equations Part I

Solve the following equations for

Question 1

Note that when calculating the basic angle we ignore the negative sign i.e. we press 0.75 into the calculator and not -0.75

We take into consideration the sign only when determining which quadrant to use

____________________

Question 2

____________________

The 2 questions above represent the most basic type of trigo equations. All complicated trigo equations can be reduced to the most basic type.

The next post will demonstrate how to solve equations where the angles are slightly more complicated such as 2x, x/2 or 2x + 74
