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=

f2sec^(2)alpha+sec^(4)alpha-2csc^(2)alpha+csc^(4)alpha=(15)/(4), then tan alpha is equal to

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।

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

(sin alpha+csc alpha)^(2)+(cos alpha+sec alpha)^(2)-7=

"If "0ltalphaltpi/2 " and " sin alpha + cos alpha + tan alpha + cot alpha + sec alpha + cosec alpha = 7 " then " "show that " sin 2 alpha " is a root of " x^(2) - 44x - 36 = 0

Show that 1 + cot^2 alpha / (1+ cosec alpha) = cosec alpha

If 3 sec alpha- 5 tan alpha= k and 6 sec alpha+k tan alpha=5 then k^(2)=
