Exercise
$\sin\left(x\right)^2+\cos\left(-\frac{12}{19}\right)^2=1$
Step-by-step Solution
Learn how to solve limits by direct substitution problems step by step online. Solve the trigonometric equation sin(x)^2+cos(-12/19)^2=1. We need to isolate the dependent variable x, we can do that by simultaneously subtracting \cos\left(-\frac{12}{19}\right)^2 from both sides of the equation. Apply the trigonometric identity: 1-\cos\left(\theta \right)^2=\sin\left(\theta \right)^2, where x=-\frac{12}{19}. Removing the variable's exponent. Cancel exponents 2 and 1.
