So whats the question my guy??
Where’s the photo to this question?
Answer:
tan cox³ / 5s
Replace ^-1 with ^(-1)
Replace x3 with x³
<h3>Step 1</h3>
Simplify
x³ / 5
Use equation to solve
tan • ((co • (s-1)) • x³ / 5)
<h3>Step 2</h3>
Take the previous equation and format it in a simpler form
tan • ((co • (s-1)) • x³ / 5) ⇒ tan • cox³ / 5s
<h3>Result</h3>
tan cox³ / 5s
