Web9 feb. 2024 · The only way to cancel the cosine function is to use the inverse cosine function, like so. This is what our equation becomes after we cancel the cosine function with its inverse cosine function. All that remains now is the use of a calculator. WebLogarithm product rule. The logarithm of the multiplication of x and y is the sum of logarithm of x and logarithm of y. log b (x ∙ y) = log b (x) + log b (y). For example: log 10 (3 ∙ 7) = log 10 (3) + log 10 (7). Logarithm quotient rule
WebThis removes the sine from one side of the equation, but puts the "arcsin" on the other side, because you have to do the same thing to both sides of the equal sign. That's the only way to remove a variable from a trig function. No multiplication, addition, or exponentiation can penetrate its borders. You have to use the inverse (arcsin) function.
