=1 trigonometry ratios formula tan θ = sin θ/cos θ cot θ = cos θ/sin θ sin θ = 1/cosec θ cos θ = sin θ/tan θ = 1/sec θ sec θ = tan θ/sin θ = 1/cos θ cosec θ = 1/sin θ also, sin (90°-θ) = cos θ cos (90°-θ) = sin θ tan (90...
Example on Sin Cos Formula Example: Find the value of sin 20° sin 40° sin 60° sin 80°. Solution: Given: sin 20° sin 40° sin 60° sin 80° This can be written as: ⇒ sin 60° sin 20° sin 40° sin 80° Substitute sin 60° = √3/2 ...
Tangent formula in trigonometry is one of the most important formulas in maths. Visit BYJU'Sto learn the formula of tangent
= period c/b = phase shift d = vertical shift similarly, for the cosine function we can use the formula a cos (bx – c) + d . thus, the graphs of all the six trigonometric functions are as shown in the below figure. video lesson maximum and minimum value of trigonometric functions ...
tan 2x we know that the formula for tan 2x is: tan 2x = 2 tan x / (1-tan 2 x) now, substitute the known values in the formula, we get tan 2x = 2(5) / (1-(5) 2 ) tan 2x = 10/ (1-25) tan 2x = 10/-24 tan 2x = -5/12. hence, the value fo tan 2x is -5/...
Tan theta is one of the trigonometric ratios which is equal to opposite / Adjacent in a triangle. Practice a few questions based on the formula for tan theta at BYJU'S.
