How to Solve Trigonometric Equations in GeoGebra
Here’s how you use GeoGebra to solve a trigonometric equation. GeoGebra has these trigonometric functions:
-
sin(x)(sine) -
asin(x)(the inverse function of sine) -
cos(x)(cosine) -
acos(x)(the inverse function of cosine) -
tan(x)(tangent) -
atan(x)(the inverse function of tangent)
