Find tan(x) and cos(x) if sin(x)=-5/9 and tan(x)<0
This is a homework problem that I found, so it shouldn’t be super difficult; I solved it pretty quickly.

It's been eons since I did any trig, but if you remember the definition of tangent and can still visualize the trig circle, it's easy to nuke it out...

I always had the hardest time with partial differentials.

Zeroth was on my tail when I did the math problems thing

Actually, calculus is simple. It's just when you start to expand it , it becomes complex...(That's why it's my favourite after conics)
