(cos^(2)(45^(@)+theta)+cos^(2)(45^(@)-theta))/(tan(60^(@)+theta)tan(30^() क्या है @)-थीटा)) बराबर...

What is (cos^(2)(45^(@)+theta)+cos^(2)(45^(@)-theta))/(tan(60^(@)+theta)tan(30^(@)-theta)) equal to ?

Evaluate : (cos^(2)(45^(@) + theta)+ cos^(2) (45^(@) -theta))/(tan(60^(@) + theta) xx tan(30^(@) - theta))+(cot30^(@) + sin 90^(@))xx (tan60^(@) -sec0^(@))

Evaluate : (cos^(2)(45+theta)+cos^(2)(45-theta))/(tan(60^(@)+theta)tan(30^(@)-theta))+cos ec(75^(@)+theta)-sec(15^(@)-theta)

The value of sin(45^(@)+theta)-cos(45^(@)-theta) is

If theta=45^(@) then (tan^(2)theta-1)/(sec^(2)theta)=

The value of sin(45^(@)+theta) - cos(45^(@)-theta) is

(2cos^(2)theta-1)((1+tan theta)/(1-tan theta)+(1-tan theta)/(1+tan theta))=?

if theta = 45^0 then tan^2 theta + 1/(sin^2 theta)

tan(2tan^(-1)sqrt((1+cos theta)/(1-cos theta)))+tan theta=0
