Is It Possible To Have Eight Trigonometric Ratios The six trigonometric ratios are sine sin cosine cos tangent tan cotangent cot cosecant cosec and secant sec In geometry trigonometry is a branch of mathematics that deals with the sides and angles of a right angled triangle Therefore trig ratios are evaluated with respect to sides and angles
Review all six trigonometric ratios sine cosine tangent cotangent secant amp cosecant The way I ve defined it so far this will only work in right triangles So if you re trying to find the trig functions of angles that aren t part of right triangles we re going to see that we re going to have to construct right triangles but let s just focus on the right triangles for now

Trigonometric ratios are ratios between the side lengths of a right triangle The six trigonometric ratios for an angle are sin cos tan csc sec and cot
Trigonometric ratios are the ratios that we can use to help find missing sides or angles of a right angled triangle What are the 3 main trigonometric ratios Sine cosine and tangent are the names of the three trigonometric ratios The trigonometric ratios for the angles 30 176 45 176 and 60 176 can be calculated using two special triangles An equilateral triangle with side lengths of 2 cm can be used to calculate accurate values
For the point x y on a circle of radius r at an angle of theta we can define the six trigonometric functions as the ratios of the sides of the corresponding triangle The sine function sin theta dfrac y r
