Cos theta sin 90-theta
WebHow to solve trigonometric equations step-by-step? To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. WebYou can use the formula sin(A−B) = sinA⋅ cosB −cosA⋅ sinB, so sin(90−θ) = sin90cosθ −cos90sinθ cosθ. Why is sin(90+ θ) = cos(θ)? This can be proved in many ways. Here I …
