" 20."sec theta-1=(sqrt(2)-1)tan theta

Solve sec theta-1=(sqrt(2)-1) tan theta .

Solve sec theta-1=(sqrt(2)-1) tan theta .

Solve sec theta-1=(sqrt(2)-1) tan theta .

IF cos theta ne 0, and sec theta-1=(sqrt2-1) tan theta then theta=

If ("sec" theta 1)- (sqrt(2)-1) "tan" theta, "then" theta =

If "sec"^(2) theta = sqrt(2) (1-"tan"^(2) theta), "then" theta=

If "sec"^(2) theta = sqrt(2) (1-"tan"^(2) theta), "then" theta=

(tan theta)/(sec theta+1)+(sec theta+1)/(tan theta)=2cos ec theta

If tan theta =(1)/(sqrt(7)) and theta is an acute angle , then ("cosec"^(2) theta - sec^(2) theta )/( "cosec"^(2) theta + sec^(2) theta =
