Question

can this be simplified to just 3?...
3cos^23t + 3sin^23t

Answer 1

it's \[cos^{23}(t)\]
right?

Answer 2

no just squared

Answer 3

Yes you can :)

Answer 4

\[3\cos ^2(3t)+3\sin ^2(3t)=3[\cos ^2(3t)+\sin ^2(3t)]=3(1)=3\]

Answer 5

perfecto! Thanks all....just part of this problem..will def be back with more trig inqueries

Answer 6

btw..what is used to show my power value in equation tool?

Answer 7

yw

Answer 8

The x^a button

Answer 9

what about this? \[\sin3t(9\sec ^{2}3t)\]

Answer 10

\[\sin (3t)(\frac{9}{\cos^2(3t)})=9\tan (3t)\sec(3t)\]

Answer 11

what about cos3t(\sin (3t)(\frac{9}{\cos^2(3t)})=9\tan (3t)\sec(3t)

Answer 12

not that
