Web22 mrt. 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.

Web26 mrt. 2016 · Imagine for a moment that you’re an engineer. You’re working with a 39-foot tower with a wire attached to the top of it. The wire needs to attach to the ground and make an angle of 80 degrees with the ground to keep the tower from moving. Your task is to figure out how far from the base of the tower the wire should attach to the ground. WebThis is because, as doctorfoxphd said, the sine of one angle is the cosine of its compliment. That's actually why it's called co-sine, because it's the sine of the complimentary angle. This is also the relationship between all the other cofunctions in trigonometry: tan (θ)=cot (90°-θ), sec=csc (90°-θ).

WebTo make theta the subject of the equation, take the inverse tangent of both sides. The inverse tangent cancels out the tangent on the left hand side of the equals side, so the equation looks as below: Comparing the two equations, the tangent has moved from one side of the equals sign to the other and has changed from tan to tan −1. gateshead civic centre opening timesWebFor a given angle θ each ratio stays the same no matter how big or small the triangle is.
