Prove Identities: cscx + cotx/tanx + sinx = cotx cscx
\n" ); document.write( "Put everything in terms of sine and cosine:
\n" ); document.write( "1/sin + (cos/sin)/(sin/cos) + sin = (cos/sin)*(1/sin)
\n" ); document.write( "1/sin + (cos^2/sin^2) + sin = cos/sin^2
\n" ); document.write( "(sin + cos^2 + sin^2)/sin = cos/sin^2
\n" ); document.write( "(sin + 1)/sin = cos/sin^2
\n" ); document.write( "sin + 1 = cos/sin
\n" ); document.write( "It's not true, not an identity.
