so i'm doing this test and I'm finished with it but i skipped these 4 probs cuz i just don't have any idea of how to do them.. can you help with any of them or at least show me how to do them.. thanks!!





All of the following are trigonometric functions of angle A except:


cos A


cst A


csc A


cot A





The trigonometric sine function is defined as:


opp/adj


opp/opp


opp/hyp


adj/hyp





sin (t + 2 ) =


sin (t)


cos (t)


tan (t)


none of the above





The linear relationship between two variables is best expressed mathematically by the equation:


y= ax2+bx+c


sin(x+y) = sinx cosy + cosx siny


A2 + B2 = C2


y = mx + b
