You can put this solution on YOUR website!
You have an equation that gives you an output of P with a given input T.
\n" ); document.write( "You're given P and need to find T.
\n" ); document.write( "Use the equation.
\n" ); document.write( "\"P=17000+%2B+4500sin%28%28pi%2AT%29%2F52%29\"
\n" ); document.write( "\"20000=17000%2B4500sin%28%28pi%2AT%29%2F52%29\"
\n" ); document.write( "\"4500sin%28%28pi%2AT%29%2F52%29=3000\"
\n" ); document.write( "\"sin%28%28pi%2AT%29%2F52%29=2%2F3\"
\n" ); document.write( "Find the angle (in radians) whose sine is 2/3.
\n" ); document.write( "\"%28pi%2AT%29%2F52=0.7297\"
\n" ); document.write( "Now solve for T.\r
