😅 You have problems with trigonometry, learn with me, how to solve basic identities ============================================ Download the TRIGONOMETRIC TABLES of the video → https://asesoriaacademica.online/inde... ============================================= Trigonometric identities are essential tools in the study of trigonometry, a branch of mathematics that focuses on the relationships between the angles and the lengths of the sides of a triangle. In this post, I will explain the 8 fundamental trigonometric identities and their importance in calculating and solving trigonometric problems. The 8 trigonometric identities are: Basic identity: coseante X=1/ Sin X secant X=1/cosX tang X=sin X/cos X cotang X=cosX/SinX sin^2 X + cos^2 X =1 cotangent X=1/tang X tang ^2 X +1 = secant ^2 X 1+cotang ^2 X=cosec^2 X Angle sum identity: sin(A+B) = sinAcosB + cosAsinB and cos(A+B) = cosAcosB - sinAsinB Angle difference identity: sin(A-B) = sinAcosB - cosAsinB and cos(A-B) = cosAcosB + sinAsinB Double angle identity: sin(2A) = 2sinAcosA and cos(2A) = cos²A - sin²A Mean angle identity: sin²(A/2) = (1-cosA)/2 and cos²(A/2) = (1+cosA)/2 Tangent identity: tanA = sinA/cosA Reciprocal identity: cscA = 1/sinA, secA = 1/cosA and cotA = 1/tanA Opposite identity: sin(-A) = -sinA and cos(-A) = cosA Identity of the Pythagorean function: sin²A + cos²A = 1 The angle sum identity is useful for computing the sine and cosine values ​​of the sum or difference of two angles. The double angle identity is especially important in calculating integrals and solving trigonometric equations. The tangent identity is useful in solving trigonometry problems involving right triangles. The reciprocal identity is useful for calculating the value of a trigonometric function from the value of another function. The opposite identity is useful for calculating the sine and cosine values ​​of negative angles. Finally, the identity of the Pythagorean function is the most important relationship between sine and cosine, since it establishes that the sum of the squares of the sine and cosine of an angle is equal to 1. In conclusion, trigonometric identities are essential tools in solving trigonometric problems and in calculating trigonometric functions. It is important to note that these identities are not only useful in trigonometry, but are also used in other areas of mathematics and in physics.
