What are the formulas in trigonometry class 10?

Class 10 Trigonometry Formulas

• sin(90° – A) = cos A.
• cos(90° – A) = sin A.
• tan(90° – A) = cot A.
• cot(90° – A) = tan A.
• sec(90° – A) = cosec A.
• cosec(90° – A) = sec A.
• sin2 θ + cos2 θ = 1 ⇒ sin2 θ = 1 – cos2 θ ⇒ cos2 θ = 1 – sin2 θ
• cosec2 θ – cot2 θ = 1 ⇒ cosec2 θ = 1 + cot2 θ ⇒ cot2 θ = cosec2 θ – 1.

What are the all formulas of trigonometry?

What is trigonometry in 10th?

Trigonometry is a branch of Mathematics that deals with the study of measuring the sides and angles of a triangle. The concept of trigonometry is completely based on right triangles. There are six trigonometric ratios namely sine, cosine, tangent, cotangent, secant, and cosecant of a reference angle.
