3. Write down the solutions to the equation \sin(\theta)=-0.2 for 360 \leq \theta \leq 720^o . (2 marks) Show answer 4. Below are the graphs of y=\sin(\theta) and y=-\cos(\theta). Estimate the solutions for \sin(\theta) = -\cos(\theta) for -360 \leq \theta \leq ...
Like cos ɸ and sin ɸ, these functions can be represented geometrically by line segments. In Figure 1, for example, tan ɸ = AL, cot ɸ = BK, sec ɸ = OL, and csc ɸ = OK. (Here, it is assumed that ɸ is acute; the trigonometric functions of other angles can be ...
Trigonometric identities are equations that are true for aright Angled triangles. Answer and Explanation: Given The given expression {eq}\sin \left( {x + y} \right) + \sin \left( {x - y} \right) = \tan x\cos \left( {x + y} \right) + \cos ...
