Typically most calculators only have the three trigonometric functions: #sin, cos, tan#. To graph the other functions you need to know that #csc (x) = 1/sin (x)# #sec (x) = 1/cos (x)# #cot (x) = 1/tan (x)# …

2) Summing the squares of equations 1 and 2: a^2 (sin^2 2Y + cos^2 2Y) = b^2 (sin^2 2X + cos^2 2X) a^2 = b^2 From question: a cos 2Y + b cos 2X = c sum equation 1 to obtain: 2a cos 2Y = c Multiply …

For an angle A in the second quadrant, sin(A)=4/5 cos(A)=-3/5 sin(2A)=-24/25 cos(2A)=-7/25 tan(2A)=24/7 We are given that sin(A)=4/5 and that angle A is in the second quadrant. Recall that …

tan (x/2 + pi/4) = sec x + tan x Use the trig identity: tan (a + b) = (tan a + tan b)/ (1 - tan a.tan b) Call t = (x/2) and develop the left side LS = tan (t + pi/4) = (tan t + tan (pi/4))/ (1 - tan t.tan (pi/4)) Trig table …
