Question: 1.Graph both sides separately for the following identities and compare them a.Sin^20+cos^20 = 1 b.csc^20 - cot^20 = 1 c.Tan^20+ 1 = sec^0 a. sin20+
1.Graph both sides separately for the following identities and compare them
a.Sin^20+cos^20 = 1
b.csc^20 - cot^20 = 1
c.Tan^20+ 1 = sec^0



a. sin20+ cos20 = 1 (Hint: Graph y1 = sin20 + cos20 and y2 = 1) b. csc20 - cot20 = 1 c. tan20 + 1 = sec20a. cos(270' + x) (Hint: use the sum/difference formulae) b. cos(4x)cos(3x) - sin(4x)sin(3x) C. sind cos 0 tanea. cos20 = cos20 - sin20 = 2cos20 - 1 = 1 - 2sin20 b. tan20 = 2tan0 1 - tan20 C. cos20 = 1 + cos20 2 (Hint: Start with the double angle side) d. tan20 = 1 - cos20 1 + cos20
