sin (90^(@)-theta) cosec (90^(@)-theta) का मान होगा : | 10 | छत्तीसगढ़ हाईस्कूल बोर्ड परीक्षा , 2...

tan^(2)(90^(@) - theta) - cosec^(2) theta =

sin theta cos(90^(@)-theta)+cos theta sin(90^(@)-theta)

sin theta cos(90^@ -theta) +cos theta sin(90^@ -theta) = ?

((cos (90 ^ (@)) - theta) sin (90 ^ (@) - theta)) / (tan (90 ^ (@) - theta))

Evaluate : sin theta cos theta - (sin theta cos (90^(@) - theta) cos theta)/( sec (90^(@) - theta)) - (cos theta sin (90^(@) - theta) sin theta)/( cosec (90^(@) - theta))

What is the value of [sin (90^@-10 theta) -cos (pi- 6 theta)]//[cos (pi//2 -10 theta) - sin (pi- 6 theta)] ? [sin (90^@-10 theta) -cos (pi- 6 theta)]//[cos (pi//2 -10 theta) - sin (pi- 6 theta)] का मान क्या है?

Show that (1)/( 1 + cos (90^(@) - theta)) + (1)/(1 - cos (90^(@) - theta )) = 2 cosec ^(2) (90 ^(@) - theta )

Write the value of "cosec"^(2)(90^(@)-theta)-tan^(2)theta.

What is the value of [1 - tan (90-theta) + sec (90 -theta)]//[tan (90 - theta)+ sec (90- theta) + 1] ? [1 - tan (90-theta) + sec (90 -theta)]//[tan (90 - theta)+ sec (90- theta) + 1] का मान क्या है?
