trig representation
Trig functions can produce displayed results that are not immediately obvious as equivalent to an expected result:
Example: int(x*sec(x^2),x); This example produces quite a lot of solution terms, and even when simplified, the result looks quite complicated: ln(((ABS(sin(x^2)^2+2*sin(x^2)+1))/(ABS(sin(x^2)^2-2*sin(x^2)+1))))/8 Given the example input, how/can the result be simplified to this form(?): (1/2)*ln(ABS(sec(x^2)+tan(x^2))) In general, is there a way to represent trig expressions in more compact terms, other than the trigx commands trigsin(), trigcos(), or trigtan()? A new command that would allow for trig compaction, like tcompact(expr,[function]), would allow students to more readily match results otherwise achieved by hand. Let me be among the first to request it! -Dale- |
