WebJan 2, 2024 · Remember that when proving an identity, work to transform one side of the equation into the other using known identities. Some general guidelines are. Begin with the more complicated side. It is often helpful to use the definitions to rewrite all trigonometric functions in terms of the cosine and sine. When appropriate, factor or combine terms. WebMove the term on the right to the left by subtracting it from both sides. tan 2 x – tan x = 0. Don’t divide through by tan x. You’ll lose solutions. Factor out tan x. tan x (tan x – 1) = 0. Set each of the two factors equal to 0. tan x = 0 or tan x – 1 = 0. Solve for the values of x that satisfy both equations.

WebSep 1, 2015 · $\begingroup$ Specifically, the decision to divide through as you did in order to "cancel" the $ \ \sin^2 \ \theta \ $ factor is based on the assumption that it is not zero.It is "safe" to do this in an equation where the factor that is being divided is known (say, from conditions in the problem) not to be zero. But if that factor could be zero, then you are …
