Question

Secx•sinx/tanx-1=0

Answer 1

True!

Answer 2

\(\Large\color{purple}{ \bf sec(x)\times \frac{sin(x)}{tan(x)}-1=0 }\)


\(\Large\color{purple}{ \bf sec(x)\times \frac{sin(x)}{ \frac{sin(x)}{cos(x)} }-1=0 }\)


\(\Large\color{purple}{ \bf sec(x)\times sin(x) \times \frac{cos(x)}{sin(x)}-1=0 }\)

\(\Large\color{purple}{ \bf \frac{1}{cos(x)}\times sin(x) \times \frac{cos(x)}{sin(x)}-1=0 }\)

sines and cosines cancel.

\(\Large\color{purple}{ \bf 1-1=0 }\)
\(\Large\color{purple}{ \bf 0=0 }\)
