# Interactive video lesson plan for: Common core math | How to Find 5 Other Trigonometric Ratios in terms of SecA | Finding trig ratio

#### Activity overview:

How to Find 5 Other Trigonometric Ratios in terms of SecA | Finding one trig ratio interms of other

00:02 2. Write all the other trigonometric ratios of ? A in terms of sec A.
00:30 What is trigonometry Identities ?
An equation is called an identity when it is true for all values of the variables involved.
An equation involving trigonometric ratios of an angle is called a trigonometric identity, if it is true for all values of the angle(s) involved
00:33 Pythagorian Identities
01:28 write sin A in terms of Sec A
01:43 Using Recipracal Identities , write cos A as (1/SecA).
02:07 Pythagorian Identity 1
03:12 SinA in terms of SecA.
03:49 Tan A in terms of SecA.
04:23 CosecA in terms of SecA.

In this video, we learn how to apply Pythagoras identities to solve Problems on Trigonometric Ratios.Using these identities, we can express each trigonometric ratio in terms of other trigonometric ratios, i.e., if any one of the ratios is known, we can also determine the values of other trigonometric ratios.
Find the trigonometric ratios cos A, tan A and sec A in terms of sin A.
