Co-function Identities I Trigonometry made easy I Learn Co-function identities in 5 minutes
Unlock the secret of Cofunctions identities in Trigonometry.
In this video ,you will learn
*What co-function identities are
*How complementary angles(90°-𝜃) relate to trigonometric functions .
*Key formulas &their proof
sin(90 − θ) = cos θ
cos(90 − θ) = sin θ
tan(90 − θ) = cot θ
cot(90 − θ) = tan θ
sec(90 − θ) = cosec θ
cosec(90 − θ) = sec θ
This lesson is perfect for high school students, exam preparation and quick revision.
