You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and …
1 + tan2x = 1 + sin2x cos2x. Learning math takes practice, lots of practice. Related Symbolab blog posts. Simplify trigonometric expressions to their simplest form step-by-step. The identity 1 + cot2θ = csc2θ is found by rewriting the left side of the equation in terms of sine and cosine. Then multiply.

Explanation:We needtan x = sin x cos xsin 2 x + cos x = 1sec x = 1 cos xTherefore,L H S = tan 2 x + 1= sin 2 x cos 2 x + 1= sin 2 x + cos 2 x cos 2 x= 1 cos 2 x= sec 2 x= R H S. sin^2 x Simplify f (x) = tan^2 x/ (1 + tan^2 x) Use trig identity: 1 + tan^2 x = 1/ (cos^2 x) f (x) = (sin^2 x)/ (cos^2 x) (cos^2 x/1) = sin^2 x. Step 3.3 Secants and cosecants of sums.3.ecitcarp fo stol ,ecitcarp sekat htam gninraeL . It certainly saves on parentheses, but gets a little confusing when you meet tan^(-1) x, which is not (tan x)^(-1) but the inverse tangent. Solution: Given: Tan x = 5. Divide both side by cos^2x and we get: sin^2x/cos^2x + cos^2x/cos^2x -= 1/cos^2x :. Multiply both sides of the equation by 2 2. 2x = arctan(1) 2 x = arctan ( 1) Simplify the right side. tan (2x)tan (x) = 1 tan ( 2 x) tan ( x) = 1.3. Giải chi tiết: Ta có: \(\begin{array}{l}{\tan ^2}x = 1 \Leftrightarrow {\sin ^2}x = {\cos ^2}x \Leftrightarrow {\cos ^2}x
Starting from: cos^2 (x) + sin^2 (x) = 1 Divide both sides by cos^2 (x) to get: cos^2 (x)/cos^2 (x) + sin^2 (x)/cos^2 (x) = 1/cos^2 (x) which simplifies to: 1+tan^2 (x) = sec^2 (x)
True Start with the well known pythagorean identity: sin^2x + cos^2x -= 1 This is readily derived directly from the definition of the basic trigonometric functions sin and cos and Pythagoras's Theorem.
