Basic Trigonometric Identities Class 10 Maths Formula Teachoo 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). Basic trigonometric identities. last updated at april 16, 2024 by teachoo. trigonometric identities are. cos 2 θ sin 2 θ = 1. 1 tan 2 θ = sec 2 θ. 1 cot 2 θ = cosec 2 θ.
