s=24.50
sinxcosx = 1/5
And by a trig identity.....
2sinxcosx = 2/5 means that
sin(2x) = 2/5
And sinx = 2/5 at about 23.58º and at 156.42º
So sin(2x) = 2/5 at [23.58º] /2 = about 11.79º and at [156.42º] / 2 = about 78.21º
16e^x = 18 divide both sides by 16
e^x = 18/16 = 9/8 take the ln of both sides
ln e^x = ln(9/8) and by a log property, we can write
x lne = ln(9/8) and lne = 1 so we have
x = ln(9/8) = about .1178
that is such an old phrase... so 2nd grade lol
you are!! :P
Why?!
I know you are but who am i?!
Pedobear: Oh Yes... Yes I do~
use a calculator
YOURE BORING!
5-1=5-1
@above w*f that never works
