Determine the sine of the angle between the vectors 5hati-3hatj, 3hati-2hatk |
Answer» Solution : `|vecaxxvecb| = sqrt(36+100+81) = sqrt(217)` `|veca| = sqrt(25+9) = sqrt(34)` `|vecb| = sqrt(9+4) = sqrt(13)` If `theta` is the ANGLE between `veca` and `vecb` then `sintheta = |vecaxxvecb|/(|veca||vecb| = sqrt(217)/(sqrt(34) sqrt(13)) = sqrt((217)/442). |
