Trigonometry can find that missing angle and distance. Or maybe we have a distance and angle and need to "plot the dot" along and up: Questions like these are common in engineering, computer animation and more. And trigonometry gives the answers!
Prove the trigonometric identity: [tex]cos\alpha+cos2\alpha+cos6\alpha+cos7\alpha=4cos\alpha{\frac{\alpha}{2}}cos{\frac{5\alpha}{2}}cos4\alpha[/tex] Solution: [tex](cos\alpha+cos7\alpha)+(cos2\alpha+cos6\alpha)=2cos4\alpha cos3\alpha +2cos4\alpha cos2\alpha =2cos4\alpha(cos3\alpha+cos2\alpha)=4cos4\alpha cos{\frac{5\alpha}{2}}cos{\frac{\alpha ...

Learn trigonometry—right triangles, the unit circle, graphs, identities, and more.
Trigonometry is a branch of mathematics that focuses on triangles. Specifically, the relationship between the angles and sides of triangles. Trigonometry is derived from the Greek word “trigonon” meaning triangle and “metron” meaning to measure. There are three main functions of trigonometry. Sine function \rightarrow \sin.
