Trigonometric Identities - Math is Fun. For the next trigonometric identities we start with Pythagoras Theorem: The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 = c 2. Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: ( a c )2 + ( b c )2 = 1.. Fundamental Trigonometric Identities - Mathematics LibreTexts.

Identity 2: The following accounts for all three reciprocal functions. Proof 2: Refer to the triangle diagram above. Note that by Pythagorean theorem .. Why is the value of r in $r=cos θ$ never negative?. The equation r = cos θ r = cos θ identifies those points whose r r -value (distance from the origin) is exactly cos cos of their θ θ value (angle from x x axis). But r r is always greater than zero (and θ θ is always between ±π ± π ), so the condition is not meaningless unless θ θ makes the cosine positive, that is θ θ is between ..
