Question

Please help me multiply this rational expression:
-4s/9t * -9s^2/2

Answer 1

9 and 9 cancel out

Answer 2

The arcsin(sqrt(2)/2) = pi/4 and 3pi/4

Answer 3

so you have left \[\frac{ (4s)(s ^{2}) }{ 2 }\]

Answer 4

which is the same as \[\frac{ 4s ^{3} }{ 2t }\]

Answer 5

i forgot the t in the first one

Answer 6

but if you simplify you should get \[\frac{ 2s ^{3} }{ }\]

Answer 7

\[\frac{ 2s ^{3} }{ t }\]

Answer 8
