Can trig functions be used for all triangles
WebIn a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. WebMar 26, 2015 · Mar 26, 2015. It depends on what you mean by "use trigonometric functions". The Law of Sines tells us that for any triangle: labelled with. a = length of the side opposite angle A. b = length of the side opposite angle B. c = length of the side … Sine, Cosine and Tangent are the names of three of the comparisons between the …

Modifying our equations from earlier, we have: ... or any triangle for that … WebWhen dealing with right triangles (triangles that have one 90 degree angle) in trigonometry, the biggest things to realize is that no matter what size the triangle is, the ratios of the lengths of the sides stay the same. So, it is very natural to give these ratios names – and that’s where the right triangle definitions of the trig functions comes from!
Web10.5. =. 0.79. To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function.
