[" 16.दिए गये चित्र में "3" tan "theta-2" sin "alpha+4" cos "alpha" का मान जात करे । "],[qquad " P "]

tan theta = (sin alpha-cos alpha) / (sin alpha + cos alpha)

If tan theta=(sin alpha- cos alpha)/(sin alpha+cos alpha) , then

If tan theta=(sin alpha- cos alpha)/(sin alpha+cos alpha) , then:

If tan theta=(sin alpha- cos alpha)/(sin alpha+cos alpha) , then:

If tan theta=(sin alpha-cos alpha)/(sin alpha+cos alpha) ,then theta is

If sin ( theta + alpha ) = cos ( theta + alpha ) , then tan theta =

If" " tan theta = (sin alpha - cos alpha)/(sin alpha + cos alpha),"prove that",2 cos^(2) theta = 1 + sin 2 alpha.

If A = 2(sin^6 theta+ cos^6 theta)- 3 (sin^4 theta+ cos^4 theta) then the value of 3 alpha such that cos alpha= sqrt((3+A)/(5+A)) is यदि A = 2(sin^6 theta+ cos^6 theta)- 3 (sin^4 theta+ cos^4 theta) है, तो 3 alpha का मान इस प्रकार ज्ञात कीजिए कि cos alpha= sqrt((3+A)/(5+A)) हो।

if sin(theta+alpha)=cos(theta+alpha) then tan alpha
