cot(tan^(-1)alpha+cot^(1)alpha)

If tan alpha + cot alpha=2 , then the value of tan^(13) alpha +cot^(13) alpha is

Prove that: (tan^(3)alpha)/(1+tan^(2)alpha)+(cot^(3)alpha)/(1+cot^(2)alpha)=sec alpha cosec alpha-2sin alpha cos alpha

If tan alpha + cot alpha=a , then the value of tan^(4)alpha + cot^(4)alpha is equal to

If tan alpha +cot alpha =a then the value of tan^(4) alpha +cot^(4) alpha=

If tan alpha + cot alpha=a , then the value of tan^(4)alpha + cot^(4)alpha is equal to

If tan alpha+cot alpha=sqrt3 , then tan^(3)alpha+cot^(3)alpha is equal to

If tan alpha+cot alpha=a, then the value of tan^(4)alpha+cot^(4)alpha is equal to

If tan alpha + cot alpha =2 , then tan^(20)alpha + cot^(20)alpha=

If tan alpha+cot alpha=m then value of tan^(4)alpha+cot^(4)alpha is
