The sine of an angle is given by the quotient between the opposite side and the hypotenuse of a right triangle. This quotient, as well as other types of quotients, are known as trigonometric ratios. These trigonometric ratios are basic tools used in trigonometry to study right triangles, e...
Hint: In this question, we have been given a condition of two vectors and we need to find the\[sine\] of the angle between them. According to the standard formula, the angle $\theta $ between two vectors \[\overrightarrow u \] and \[\overrightarrow v \;\] i...
The SIN function is used to determine the sine of angles in Excel. Syntax: =SIN(number) Arguments Explanation: ArgumentRequired/OptionalExplanation number Required Angle in radians to calculate the sine of the given angle. Return Parameter: Sine value of the given angles. What is the Sine...
Measuring angles without a protractor is one of the fundamental aspects of geometry. Sine, cosine, and tangent are three concepts that will allow you to calculate an angle based solely on the lengths of two sides of a right triangle. You can form a right triangle out of any single angle w...

To calculate the other angles, we need the sine, cosine and tangent. In fact, the sine, cosine and tangent of an acute angle can be defined by the ratio between sides in a right triangle. Just like every other triangle, a right triangle has three sides. One of them is the hypothenus...
Subtract the angle between the force and the resultant vector you want to calculate from 90. If, for instance, the force acts at a 30-degree angle from the object's direction of motion then 90 – 30 = 60. Step 2 Find the sine of this angle. With the example for Step 1, sin (60...
The y-coordinate corresponds to the exact value of the sine function for that angle. In a unit circle, a straight line traveling right from the center of the circle will reach the circle's edge at the coordinate (1, 0). Here are the coordinates if the line went in the other ...
Excel has built-in trigonometric functions that make it easy to find the cosine, sine, and tangent of a right-angle triangle — a triangle containing an angle equal to 90 degrees. The only problem is that these functions requireangles expressed in radians, not degrees. While radians, a unit...
How can one prove that the exterior angles of polygon always add up to 360 degrees? Explain the sine and cosine functions. What is the sine rule? How do we prove that the measure of an inscribed angle (of an intercepted arc) is half of the central angle (or the measure of the interc...
