Did you know?
WebJul 25, 2016 · If cos θ = (-5/13), then θ should be in quadrant II or III. The given says sin θ < 0, so θ should be in quadrant III. In this case, tan θ should be equal to number greater than zero. Hence we get sqrt of (13^2 - 5^2 ) equal to 12. tan θ should be equal to A 12/5. WebThe cosine function cosx is one of the basic functions encountered in trigonometry (the others being the cosecant, cotangent, secant, sine, and tangent). Let theta be an angle measured counterclockwise from the x …
