How to solve for theta with cos and sin
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. WebWith only the sides given, you'd have to solve for an angle using the law of cosines. If the triangle had a right angle, you could use the inverse trig functions. The law of cosines is: c^2 = a^2 + b^2 - 2*a*c*cos (C) a, b, and c are sides of a triangle, and C is the angle included …
