WebSine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is To calculate them: Divide the length of one side by another side Example: What is the sine of 35°?

WebExample 1: Determine the value of the length of the base of a right-angled triangle if cos x = 0.8 and the length of the hypotenuse is 5 units using cosine function formula. Solution: We know that cos x = Base/Hypotenuse. We have cos x = 0.8, Hypotenuse = 5 units. Therefore, 0.8 = Base/5. ⇒ Base = 5 × 0.8 = 4. WebJan 27, 2024 · Inverse trig functions are just the opposite of trig functions. The inverse of tangent is written as: arctan x (which can look like atan x) or tan − 1 x (or tan inverse x ). Sine and cosine work the same way; just replace “tangent” with either “sine” or “cosine.”. If we apply this to our example, we get: x = arctan 7 18. oldfield road altrincham
