Cotangent (cot) is a ratio of the adjacent and opposite sides. That is, {eq}\cot(\theta) = \dfrac{\text{adjacent}}{\text{opposite}} {/eq}. The following two examples demonstrate how to find the trigonometric ratios of a given angle in a right triangle. We will use the steps and ...

Over to James. How do you find exact values for the sine of integer angles? Here is one way of going about it. Background Let’s find someexact valuesusing some well-known triangles. Then we’ll use these exact values to answer the above challenges. ...
So we need to find the inverse Sine of the ratio of the sides.Use the formula:=ASIN(A2/C2)A2/C2 : it returns the ratio of the sides where value of the sides is given in as cell referenceGiven the ratio of the sides as input to the ASIN function in excel and Press Enter....
Tangent is the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle, which gives us the equation: We use tangent to find the length of the side of a right triangle that is adjacent to an acute angle with a known measure as long as ...
