Question

solve cot theta - tan theta - costheta +sintheta = 0

Answer 1

cottheta - tantheta = costheta - sintheta

cos/sin - sin/cos = cos - sin

(cos² - sin²)/sincos = cos - sin

cos² - sin² = (cos - sin)(sincos)

(cos + sin)(cos - sin) = (cos - sin)(sincos)

cos + sin = sincos

cos/(sincos) + sin/(sincos) = 1

1/sin + 1/cos = 1

cosec + sec =1
