Answer 5

how do u simplify sincos

Answer 6

that part doesnt, sin^2 + cos^2 =1 so you get
2sincos+1/sin^2-cos^2

Answer 7

but it can be implified even more

Answer 8

numerator= (sin+cos)^2
denominator=(sin+cos)(sin-cos) [difference of squares]
sin+cos/sin-cos is as simple as it gets

Answer 9

MCronin is correct!

Answer 10

I don't get it..why isn't it (a+b)^2??? Someone explain me plsss

Answer 11
