One way to convert sin's to cos's is to use sin^2(x) + cos^2(x) = 1 or cos^2(x) = 1 - sin^2(x) The sin's on the left are not squared. But from the factoring pattern I know I can get 1 - sin^2(x) in both denominators by multiplying each fraction by appropriate expressions (as you'll see shortly).

2 sinx = sin 2x ⇐⇒ 2 sinx = 2 sinxcosx ⇐⇒ 2 sinx(1 − cosx)=0. ⇐⇒ sinx =0 eller cosx = 1. Lösningarna till den andra av dessa två ekvationer är desamma som

If so under what subject do I find more information about this. Jun 23, 2018 20.7K answers. 179.2M people helped. Answer: Step-by-step explanation: \* sin 2x = 2sinxcosx *\. \* By trigonometric identity : 1 = sin² x + cos² cos2(x) + sin2(x) = 1. This important relation is called an identity. Identities are equations which are true for all values of the variable.
