Question

@dude can you help me with a few trig proofs pleaseeee

Answer 1

\[(\cos(x)+1)/(\sin^3(x))=(\csc(x)/(1-\cos(x))\]
so yk that \[a/b = c/d\] is the same as
\[ad=bc\]
in that case we can rearrange the original equation
\[(\cos(x)+1)(1-\cos(x)=(\csc(x)(\sin^3(x)))\]

Answer 2

next step, lets look at the left side, this is similar to the format (a + b) (b - a) where a is (cos(x)) and b is 1.
Can you simplify the left side?

Answer 3

cosx -cos^2 x +1 -cosx
= 1-cos^2x
ohhhhh which equals sin^2 x

Answer 4

yes ma'am, while on the right side csc(x) = 1/sin(x)
1/sin(x) * sin^3(x) = sin^2(x)'
u just proved it

Answer 5

hehe
thank you so muchhhhhhhhhhhh xdxdxdxdxdxdd <3
