Question

prove that..... plz answer fast

Answer 1

[tex](cot \theta/cosec\theta+1)+(cosec\theta+1)/cot\theta ((cos\theta/sin\theta)/(1/sin\theta)+1)+((1/sin\theta)+1/(cos\theta/sin\theta)) ((cos\theta/sin\theta)/(1+sin\theta)/sin\theta)+((1+sin\theta)/sin\theta/(cos\theta/sin\theta)) (cos\theta/(1+sin\theta)+(1+sin\theta)/cos\theta) (cos ^{2}\theta+(1+sin\theta )^{2} )/(cos\theta*(1+sin\theta)) (cos ^{2}\theta+1+sin ^{2}\theta+2*sin\theta)/(cos\theta*(1+sin\theta)) 2+2sin\theta/cos\theta(1+sin\theta)

2(1+sin\theta) / cos\theta(1+sin\theta),

2/cos\theta,
hence prove,2sec\theta [/tex]
