There are six trigonometric ratios. Although applicable for any angle, they are usually introduced in the context of a right angled triangle. The full names of the main three ratios are sine, cosine, tangent. The other three ratios are reciprocals, which are cosecant, secant and cotangent, respectively.
Suppose ABC is a triangle which is right angled at B. Thus AC is the hypotenuse.
sin(A) = BC/AC = cos(C)
cos(A) = AB/AC = sin(C)
tan(A) = BC/AB

What are ratios that have same value?
Equivalent ratios.
What are ratios that are equal?
They are called equivalent ratios.
What does it mean when two ratios form a proportion?
When two ratios form a proportion, the ratios are equal
How do you find the sides of a right triangle with only one side and one angle?
It is very easy just apply the trignometric ratios ull get the second side to find the third side u will need to use phytagoras theorem. good luck.
What are the trignometric ratios?
There are three trigonometrical ratios for finding the angles and lengths of a right angled triangle and they are tangent, cosine and sine usually abbreviated to tan, cos and sin respectively. tan = opp/adj cos = adj/hyp sin = opp/hyp Note that: opp, adj and hyp are abbreviations for opposite, adjacent and hypotenuse sides of a right angled triangle respectively.
How do you find x in a trignometric functions?
find x. given is 14 and a 90 degree angle
Express all the trignometric ratios in terms of COS A?
Provided that any denominator is non-zero, sin = sqrt(1 - cos^2)tan = sqrt(1 - cos^2)/cos sec = 1/cos cosec = 1/sqrt(1 - cos^2) cot = cos/sqrt(1 - cos^2)
Is the principal trignometric functions are injective?
Yes, that is why they are called "principal". The domains are restricted so that the functions become injective.
What are equivlent ratios?
when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios
