Dividing fractionsuibs= by fract

[lektor]

hi, while doing trig identities I've found I am going to need to understand this..


cosx + sinx/cosx
---------------
1/cosx

sorry latex confused me so this is the best i can do :O



this is not an actuall question but just what i need help with :]

What in particular do you need to understand about it?

 

[ahrkron]

Do you need to reduce the expression? What can you do with it?

I presume you mean \frac{cos(x)+ \frac{sin(x)}{cos(x)}}{\frac{1}{cox(x)}

Dividing by a fraction is the same as inverting the fraction and multiplying:
(cos(x)+ \frac{sin(x)}{cos(x)})(cos(x). Does that help?
