sin θ = \frac{m^{2} - n^{2}}{m^{2} + n^{2}}

tan θ

tan θ + sin θ = m

tan θ - sin θ = n,

then which of the following relation between

m, n

Q. State True or False.

\sqrt{m^{2} n^{2}} \times \sqrt[6]{m^{2} n^{2}} \times \sqrt[3]{m^{2} n^{2}}

= m^{2} n^{2}

m = cos A - sin A

n = cos A + sin A

\frac{m^{2} + n^{2}}{m^{2} - n^{2}} = - \frac{1}{2} sec A . cos e c A = - \frac{(cot A + tan A)}{2}
