The tangent function is a trigonometric function that is derived from the sine and cosine functions. In right-angled triangles, the tan of an angle (θ) is the ratio of the side opposite the angle to ...

This calculator is made in C and doesn't use math.h library. It works using Taylor Series to calculate the cos of the angle (in radians or degrees) and of the complementary that is the sin of the ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...

Sine, often denoted by the abbreviation “sin,” is an important trigonometric function that arises frequently in mathematics, science, and engineering. It provides information about the ratios of the ...

This version is used to calculate lengths. Calculate the length BC. Give the answer to three significant figures. Use the form \(a^2 = b^2 + c^2 - 2bc \cos{A}\) to calculate the length. \(\text{BC}^2 ...
