In trigonometry formulas, we will learn all the basic formulas based on trigonometry ratios (sin,cos, tan) and identities as per Class 10, 11 and 12 syllabi. Also, find the downloadable PDF of trigonometric formulas at BYJU'S.
Trigonometry formulas are sets of different formulas involving trigonometric identities, used to solve problems based on the sides and angles of a right-angled triangle. Additionally, there are many trigonometric identities and formulas that can be used to simplify expressions, solve equations, and evaluate integrals.

While there isn’t a definitive list of “7 trigonometric formulas,” this section covers the most crucial and commonly used formulas, along with their applications. 1. Right Triangle Definitions (SOH CAH TOA): sin(θ) = opposite / hypotenuse. cos(θ) = adjacent / hypotenuse. tan(θ) = opposite / adjacent. 2.

In Trigonometry Formulas, we will learn. Basic Formulas. sin, cos tan at 0, 30, 45, 60 degrees. Pythagorean Identities. Sign of sin, cos, tan in different quandrants. Radians. Negative angles (Even-Odd Identities) Value of sin, cos, tan repeats after 2π. Shifting angle by π/2, π, 3π/2 (Co-Function Identities or Periodicity Identities)
cot θ = 1/tan θ. sin θ = 1/cosec θ. cos θ = 1/sec θ. tan θ = 1/cot θ. Pythagorean Identities. According to the Pythagoras theorem, in a right triangle, if ‘c’ is the hypotenuse and ‘a’ and ‘b’ are the two legs then c2 = a2 + b2. We can obtain Pythagorean identities using this theorem and trigonometric ratios.
