f `2 sec^2 alpha+sec^4alpha-2csc^2alpha+csc^4alpha=15/4` , then `tan alpha` is equal to

If 2sec^2 alpha- sec^4 alpha-2 cosec^2 alpha+cosec^4 alpha=15/4 then tan alpha=

If 2sec^2 alpha- sec^4 alpha-2 cosec^2 alpha+cosec^4 alpha=15/4 then tan alpha=

If 2sec^2 alpha- sec^4 alpha-2 cosec^2 alpha+cosec^4 alpha=15/4 then tan alpha=

2sec^(2)alpha-sec^(4)alpha-2csc^(2)alpha+csc^(4)alpha=

If 2sec^(2)alpha-sec^(4)alpha-2cos ec^(2)alpha+cos ec^(4)alpha=(15)/(4) then tan alpha=

2sec^(2)alpha-sec^(4)alpha-2cos ec^(2)alpha+cos ec^(4)alpha=cot^(4)alpha-tan^(4)alpha

If tan alpha=2 , then the value of (cosec^2 alpha-sec^2 alpha)/(cosec^2 alpha+sec^2 alpha) is यदि tan alpha=2 है, तो (cosec^2 alpha-sec^2 alpha)/(cosec^2 alpha+sec^2 alpha) का मान ज्ञात करें।

tan alpha+2tan2 alpha+4tan4 alpha+8cot8 alpha is equal to :
