Question

find the value of cos squared theta minus one upon sin squared theta

Answer 1

hey frnd.....
heres your answer
$( { \cos( \alpha ) }^{2} - 1) \div { \sin( \alpha ) }^{2} \\ now \: we \: know \: that \: { \cos( \alpha ) }^{2} + { \sin( \alpha ) }^{2} = 1 \\ then \: { \cos( \alpha ) }^{2} = 1 - { \sin( \alpha ) }^{2} \\ put \: this \: in \: the \: eqation \: we \: get\\ (1 - { \sin( \alpha ) }^{2} - 1) \div { \sin( \alpha ) }^{2} \\ - { \sin( \alpha ) }^{2} \div { \sin( \alpha ) }^{2} \\ - 1$
