Using this relation, it is possible to calculate the needed distances without having to measure them directly. The tools that link angles to distances are trigonometric functions. They are introduced in this chapter while solving practical problems below鈥...
The trigonometric ratios we have studied till now are the ratios of acute angles in any right-angled triangle. What about trigonometric ratios for any angled triangle. When we talk about a normal triangle with any degree of angle, we extend our term to trigonometric functions. The following ...
Trigonometric functions allow us to calculate unknown values of a right-angled triangle from known parameters. Imagine you’re standing on the ground, looking up at a tall tree. It would be very difficult to measure the height of the tree from the ground. But if we know the angle at which...
In this section we look at how to integrate a variety of products of trigonometric functions. These integrals are called trigonometric integrals. They are an important part of the integration technique called trigonometric substitution, which is featured in Trigonometric Substitution. This technique ...

understanding the fundamental trigonometric functions: sine, cosine and tangent. These will help you solve for unknown quantities of triangles. You'll also get practice identifying the basic Pythagorean identities. Additionally, there are flashcards to help you study the Law of Sines and the Law of...

Inverse Trigonometric Functions An expression likeSin(y) = xy = ArcSin(x), where the expressionArcSin(x)is the called theinverse sineof x. The inverse trigonometric functions have their own rules for differentiation. Example 13: Find the value of dy/dx for the equation y = ArcCos(x) when...
In this text, the reader will learn that all the basic functions that arise in calculus such as powers and fractional powers, exponentials and logs, trigonometric functions and their inverses, as well as many new functions that the reader will meet are naturally defined for complex arguments. ...
