Question

Yang 1 b dongg plisss...thanks before ;)

Answer 1

(sin^2/cos^2)(tan-cos.cot) = sin(tan^2 - cos)
(sin^2/cos^2)[(sin/cos) - cos(cos/sin)] = sin(tan^2 - cos)
(sin^3/cos^3) - (sin) = sin(tan^2 - cos)
sin [(sin^2/cos^3) - 1] = sin(tan^2 - cos)
sin [(tan^2/cos) - 1] = sin(tan^2 - cos)
sin (tan^2 - cos) = sin(tan^2 - cos) ----> TERBUKTI
