WebSep 11, 2024 · Another way to do this is to first find cos θ. This is easier if you recognise small Pythagorean triads. ;) Let y / r = sin θ and x / r = cos θ, where r 2 = x 2 + y 2. We have sin θ = 5 / 13, so x 2 = 13 2 − 5 2 = ( 13 + 5) ( 13 − 5) = 18 ⋅ 8 = 12 2 thus cos θ = 12 / 13. Now, we know that sin ( 2 θ) = 2 sin θ cos θ. But that's the middle term of
WebOct 23, 2024 · How do you solve cos θ = sin θ? Trigonometry Trigonometric Identities and Equations Solving Trigonometric Equations 1 Answer José F. Oct 23, 2024 The answer is ± π 4 Explanation: cos(θ) = sin(θ) cos(θ) = cos( ± π 2 −θ) by trigonometric equivalences θ = ± π 2 − θ +2kπ with k any integer 2θ = ± π 2 +2kπ θ = ± π 4 + kπ Answer link WebYou want to substitute a function in there, so we choose tan (theta) since it is related to sec (theta) by tan^2 (theta) + 1 = sec^2 (theta). So, in order for this substitution to work out okay, you're letting x=a*tan (theta) so that when you write it out, you will end up with a^2+ (a*tan (theta))^2 in your denominator.
WebJul 12, 2024 · Answer. In addition to the Pythagorean Identity, it is often necessary to rewrite the tangent, secant, cosecant, and cotangent as part of solving an equation. Example 7.1. 4. Solve tan ( x) = 3 sin ( x) for all solutions with 0 ≤ x < 2 π. Solution. With a combination of tangent and sine, we might try rewriting tangent.

WebMar 22, 2016 · For question #1 you need to use the formula: sin θ = sin a θ = { 2 k π + a, k ∈ Z or 2 k π + π − a, k ∈ Z and in the second case cos θ = cos a θ = 2 k π ± a, k ∈ Z In our example, in the first case a = 99 π / 5. Take advantage of the inequality to find all the appropriate k ∈ Z in order to define θ.
