Finding trigonometric ratios of complementary angles (Examples) (Telugu) | Trigonometry | 10th grade

Описание: In this video, we guide you through clear, step-by-step worked-out examples based on the six trigonometric cofunction identities—the relationships that connect sine, cosine, tangent, cotangent, secant, and cosecant for complementary angles.

These identities show how trig functions “pair up” when angles add up to 90°:
sin(θ) = cos(90° − θ)
cos(θ) = sin(90° − θ)
tan(θ) = cot(90° − θ)
cot(θ) = tan(90° − θ)
sec(θ) = csc(90° − θ)
csc(θ) = sec(90° − θ)

Through multiple examples, you’ll learn exactly how to apply these identities to simplify expressions, evaluate trig functions, and solve problems with confidence.
