Given csc theta = (2 sqr3)/(3) and -270 less than 0 less than 180
\n" ); document.write( "determine the exact values of theta\r
\n" ); document.write( "\n" ); document.write( "my work:\r
\n" ); document.write( "\n" ); document.write( "(2 sqr3)/3 = 1/sin theta
\n" ); document.write( "sin theta * (2sqr3)/3 =1
\n" ); document.write( "sin theta = 1/ (2sqr3/3)
\n" ); document.write( "sin theta = 3/ (2sqr3)
\n" ); document.write( "when I try to find the inverse of sin theta to find the angle, it gives me an error
\n" ); document.write( "
You're on the right track, but need guidance.
\n" ); document.write( "You're correct in that: \"sin+%28theta%29+=+3%2F%282sqrt%283%29%29\". However, you MUST RATIONALIZE the denominator.
\n" ); document.write( "We then get: \"sin+%28theta%29+=+3sqrt%283%29%2F%282sqrt%283%29+%2A+sqrt%283%29%29\" =====> \"sin+%28theta%29+=+3sqrt%283%29%2F%282+%2A+3%29\" =====> \"sin+%28theta%29+=+3sqrt%283%29%2F6\" =======> \"cross%283%29sqrt%283%29%2F2cross%286%29\" ======> \"sin+%28theta%29+=+sqrt%283%29%2F2\"
\n" ); document.write( "Now, this is the answer since the EXACT value is required, and since \"matrix%281%2C3%2C+-+270+%3C+theta+%3C+180%2C+%22=%22%2C+90%5Eo+%3C+theta+%3C+180%5Eo%29\",
\n" ); document.write( "then \"sin+%28theta%29+=+sqrt%283%29%2F2\" is in the 2nd quadrant, where sin is positive (> 0) \n" ); document.write( "
\n" );
