WebJul 11, 2012 · Science Advisor. Gold Member. 5,196. 38. Clearly theta is part of a 3-4-5 triangle, which means that cos (theta) = 4/5. These can all be solved by employing a set of trigonometric identities known as the sum and difference formulae, which tell you how to compute the sine or cosine of the *sum* (or difference) of two angles. WebVerifying a Trigonometric Identity Involving sec2θ Verify the identity sec2θ − 1 sec2θ = sin2θ Analysis In the first method, we used the identity sec2θ = tan2θ + 1 and continued to simplify. In the second method, we split the fraction, putting both terms in the numerator over the common denominator. WebJul 23, 2024 · 1. Evaluate the following. The angle is not commonly found as an angle to memorize the sine and cosine of on the unit circle. 2. Write the expression in terms of common angles. We know the cosine and sine of common angles like and It will therefore be easier to deal with such angles. [2] 3. date of birth jose rizal
