In trigonometry formulas, we will learn all the basic formulas based on trigonometry ratios (sin,cos, tan) and identities as per Class 10, 11 and 12 syllabi. Also, find the downloadable PDF of trigonometric formulas at BYJU'S.

We are given a trigonometric ratio of cos 4 θ and we have to change it into a ratio with unit θ means to change it into a ratio where the θ is in unit form. To do so we will see what the ways …

In the given problem, we have to find the value of cos 4 θ − sin 4 θ. So, we have, cos 4 θ − sin 4 θ Using the algebraic identity (a 2 − b 2) = (a − b) (a + b), we get, ⇒ (cos 2 θ) 2 − (sin 2 θ) 2 ⇒ (cos 2 θ − sin 2 θ) (cos 2 θ + sin 2 θ) Now, we subtract the trigonometric identity cos 2 x …
