Solve for the missing angle by using the arcsin, arccos or arctan function of your calculator (usually labeled as “sin-1,”“cos-1” and “tan-1”). For example, to find angle A given that side a = 3 and side b = 4, since tanA = 3/4 , you would enter arctan(3/4) into...
Sin cos tan values are the primary functions in trigonometry. Learn the values for all the angles, along with formulas and table. Also, learn to find the values for these trigonometric ratios.
In fact, it can be done with pencil and paper, if you use a simple identity from trig. You claim to have the problem: e*sin(gammaL) + thetaC*cos(gammaL) == 0 where e and thetaC are known. Jut rewrite it as -thetaC/e = sin(gammaL)/cos(gammaL) Now if you recognize th...
Plugging our values from step 1 into the trigonometric ratio formulas, we have the following: $$\boxed{\begin{align} \sin{\theta} &= \dfrac{\rm{opp}}{\rm{hyp}} &= \dfrac{3}{5} \\\ \cos{\theta} &= \dfrac{\rm{adj}}{\rm{hyp}} &= \dfrac{4}{5} \\\ \tan{\theta} &...

Tan 90° = Sin 900/ Cos90° From thetrigonometric table, we know, Sin 90° = 1 And, Cos 90° = 0 ∴ Tan 90°= 1/0 = Undefined That means, we cannot define Tan 900value. For a unit circle,which has a radius equal to 1, we can derive the tangent values of all the degrees...
