Simplify the problem: Sin theta Sec Theta

kherson [118]

Answer:

$\tan \theta$

Step-by-step explanation:

We have to simplify the following expression as given by

$\sin \theta \times \sec \theta$

= $\frac{\sin \theta}{\cos \theta}$

= $\tan \theta$ ( Answer )

Because, we know that $\sec \theta =\frac{1}{\cos \theta}$ and $\tan \theta = \frac{\sin \theta}{\cos \theta}$

If we consider $\sin \theta = \frac{Perpendicular}{Hypotenuse}$ and $\sec \theta = \frac{Hypotenuse}{Base}$ ,

then $\sin \theta \times \sec \theta = \frac{Perpendicular}{Hypotenuse}\times \frac{Hypotenuse}{Base} = \frac{Perpendicular}{Base}= \tan \theta$

How do you Simplify x/7x +x^2

tekilochka [14]

I'm assuming you meant to write $\frac{x}{7x+x^2}$

If so, then factor out an 'x' from the denominator and cancel

 $\frac{x}{7x+x^2}$

 $\frac{x}{x(7+x)}$

 $\frac{1}{7+x}$

So the answer is $\frac{1}{7+x}$
