Question

If x sin cube + y cos theta equals to sign into cos theta and x sin theta equals to y cos theta prove that x square + y square = 21

Answer 1

Answer:

sin(-x) = -sin(x)

csc(-x) = -csc(x)

cos(-x) = cos(x)

sec(-x) = sec(x)

tan(-x) = -tan(x)

cot(-x) = -cot(x)

Answer 2

Answer:

❤️❤️sin(-x) = -sin(x)

sin(-x) = -sin(x)csc(-x) = -csc(x)

sin(-x) = -sin(x)csc(-x) = -csc(x)cos(-x) = cos(x)

sin(-x) = -sin(x)csc(-x) = -csc(x)cos(-x) = cos(x)sec(-x) = sec(x)

sin(-x) = -sin(x)csc(-x) = -csc(x)cos(-x) = cos(x)sec(-x) = sec(x)tan(-x) = -tan(x)

sin(-x) = -sin(x)csc(-x) = -csc(x)cos(-x) = cos(x)sec(-x) = sec(x)tan(-x) = -tan(x)cot(-x) = -cot(x)❤️❤️
