Help with proving the following

Mathematics
1 answer:
Galina-37 [17]2 years ago
4 0

Hello and Good Morning/Afternoon

<u>Let's take this problem step-by-step</u>:

<u>First step</u>

⇒ consider the fact cotθ = 1 / (tanθ)

 \frac{1+tanx}{1+cotx} =\frac{1+tanx}{1+\frac{1}{tanx} }

<u>Second step</u>

⇒ form a common denominator for the fraction in the 'denominator'

\frac{1+tanx}{1+\frac{1}{tanx} } =\frac{1+tanx}{\frac{tanx+1}{tanx} }

<u>Let's flip over the fraction on the denominator</u>

\frac{1+tanx}{\frac{tanx+1}{tanx} } =(1+tanx) * \frac{tanx}{1+tanx} =tanx

<u>And there you go, you have </u><u>proved the statement</u> by <u>following these steps!</u>

 *note, I used 'x' because the equation creator didn't have 'θ' symbol

Hope that helps!

What is the slope between the points 5,-1 and -2,-3?
pishuonlain [190]
To find slope, use the equation (y2-y1)/(x2-x1). In your case, the equation is going to look like (-3 - -1)/(5 - -2) or (-3 +1)/(5 + 2), and that simplifies to -2/7.
