1. 20° is a third of 60°, for which the value of the tangent is well known to be √3. Let us denote x: = tan(20°). Then, by the addition formula, tan(40°) = 2x 1 − x2, and tan(60°) = x + 2x 1 − x2 1 − x 2x 1 − x2 = 3x − x3 1 − 3x2 = √3, or x3 − 3√3x2 − 3x + √3 = 0. It turns out that this cubic equation cannot be
By using power rule and chain rule, f' (x) = 2 tan x · d/dx (tan x) We know that the derivative of tan x is sec 2 x. So. f' (x) = 2 tan x · sec 2 x. Answer: The derivative of the given function is 2 tan x · sec 2 x. Example 2: What is the derivative of tan x with respect to sec x.
Consider tan 3 x = tan 2 x + x. The formula to find the tangent of summation of two angles is. tan A + B = tan A + tan B 1-tan A tan B. Substituting A = 2 x, B = x
e. In trigonometry, the law of tangents or tangent rule [1] is a statement about the relationship between the tangents of two angles of a triangle and the lengths of the opposing sides. In Figure 1, a, b, and c are the lengths of the three sides of the triangle, and α, β, and γ are the angles opposite those three respective sides.

2 tan 2 θ. Explanation for the correct option: Evaluating the given expression: Given expression is tan π 4 + θ-tan π 4-θ. We know that tan (A + B) = tan A + tan B 1-tan A tan B. Applying this identity, we get

sin, cos and tan. The three most useful derivatives in trigonometry are: ddx sin(x) = cos(x) ddx cos(x) = −sin(x) ddx tan(x) = sec 2 (x) Did they just drop out of the sky? Can we prove them somehow? Proving the Derivative of Sine. We need to go back, right back to first principles, the basic formula for derivatives: dydx = limΔx→0 f(x+Δx
