Calculate the values of sin L, cos L, and tan L. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions. Their usual abbreviations are sin(θ), cos(θ) and tan(θ), respectively, where θ denotes the angle. Note: sin 2 θ-- "sine squared theta" -- means (sin θ) 2. Problem 3.

cos θ ≈ 1 − θ2/2 at about 0.664 radians ( 38°)  Divide by costheta. You get Sin(theta)/Cos(theta) + Cos(theta)/cos(theta) =o [Sinx /cosx = tanx (a law of trigs)] so the same as tan(theta) + 1=0. So tan(theta)=-1. 2. KCET 2011: If A= [ cos θ sin θ - sinθ cos θ ] then A ⋅ A' is (A) I (B) A (C) -A (D) A2. Check Answer and Solution for above que.
