Even allowing for calculator rounding errors, we can be confident our answer is correct. List of all sines of integer degrees from 1° to 90° WebApr 2, 2024 · So, we get x = cos 48 ∘ − cos 48 ∘. ⇒ x = 0. So, we have found the value of cos 48 ∘ − sin 42 ∘ as 0. ∴ The value of cos 48 ∘ − sin 42 ∘ is 0. Note: Whenever we get this type of problem, we should try to convert both the trigonometric functions into the same trigonometric functions in order to reduce the calculation time.

If tan A = cot B, prove that A + B = 90°. WebThe ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides. richard hatch movies
