Web0.342 0.940 = 0.364. Now, it is possible to use the angle sum and difference formulas for tangent to find the value of tangent at 2 ∘ and 38 ∘. Recall that the tangent of the sum of two angles x and y is: t a n ( x + y) = t a n x + t a n y 1 − t a n x t a n y. Therefore, since 38 = 18 + 20, the tangent of 38 degrees is: WebFree Derivative Sum/Diff Rule Calculator - Solve derivatives using the sum/diff rule method step-by-step ...
