Using pythagorean identities,tan(sin^-1(-5/13))= tan(arcsin(-5/13))

Let A = arcsin(-5/13) = -arcsin(5/13)

Thus, sin A = -5/13 and cos A = sqrt(1 - (5/13)^2) = 12/13.= tan(A)= sin(A) / cos(A)= -5/13 / (12/13)= -5/12

Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,

\bf \textit{Logarithm Cancellation Rules}\\\\&#10;log_a a^x\implies x\qquad \qquad a^{log_ax}=x\\\\&#10;-------------------------------\\\\&#10;10^{log(3)}+log(100)\implies 10^{log_{10}(3)}+log_{10}(100)\implies 3+log_{10}(10^2)&#10;\\\\\\&#10;3+2\implies 5
