Trigonometric Identities And Equations
Gbogbo ọrọ náà
Trigonometry has a hidden web of relationships connecting sine, cosine and tangent. These identities let you rewrite expressions, prove statements, and unlock equations that look impossible at first. The most famous of all, \(\sin^2\theta+\cos^2\theta=1\), is really just Pythagoras' theorem in disguise.
In this lesson you will meet the key identities, learn how to prove an identity by working on one side until it matches the other, and solve trigonometric equations across a given range. A crucial new idea is that such equations usually have more than one solution in a full turn, so you must find them all.
