Trigonometry Formulas Trig Applications Lesson Summary FAQs Activities What are the three formulas of trigonometry? In a right-angled triangle, if an angle, x, is specified: sin(x) is the ratio of the side opposite the angle and the hypotenuse, cos(x) is the ratio of the side adjace...
Before beginning, try to remember below trigonometry formulas. sin x = cos (90° – x) cos x = sin (90° – x) tan x = cot (90° – x) cot x = tan (90° – x) sec x = cosec (90° – x) cosec x = sec (90° – x) ...
Just as in the formulas below, you will observe that the sin function is related to the cos function and vice versa. Further, the is function is related to the tan function and vice versa. The other one that is sec function is also related to the cot function and vice versa. sin x ...
Trigonometry formulas list for all the classes from 10 to 12 are accumulated here. List of all important formulas with reference to a right-triangle and a unit circle provided here at BYJU'S.
1. Trigonometry Ratio Formulas sin θ = Opposite Side/Hypotenuse cos θ = Adjacent Side/Hypotenuse tan θ = Opposite Side/Adjacent Side cot θ = 1/tan θ = Adjacent Side/Opposite Side sec θ = 1/cos θ = Hypotenuse/Adjacent Side

Now we make use of the formulasAddition , Subtraction There are other triangles, but I am lazy. Let's see how far you can get with just those I've done so far and a few simple laws (so you can add and subtract and multiply and divide angles). Please note that getting 1/3 of ...
