Best ResponseYou've already chosen the best response.3the hypoteneuse is always +ve in the 4th, 4 is ve, 3 is +ve the CAST thing allows you to predict the sign of the trig function without even looking that far, eg only tan is ve in the 3rd of course that is because, in the 3rd, both opposite and adjacent are ve [and hypoteneouse is always +ve, as mentioned] but the CAST shortcut allows you to "just know"
