यदि आव्यूह `A = [[cos theta, sin theta],[-sin theta, cos theta]]` हो, तो `A A^(T)` ज्ञात कीजिए।

If A=[{:(cos theta, sin theta),(-sin theta, cos theta):}] then "A A"^(T) is :

If 5 cot theta=3 , find the value of (6 sin theta-3cos theta)/(7sin theta+3cos theta) . यदि 5 cot theta=3 ,है, तो (6 sin theta-3cos theta)/(7sin theta+3cos theta) का मान ज्ञात कीजिए ।

If A = [(cos theta, sin theta),(-sin theta, cos theta)] and B = [(sin theta, - cos theta), (cos theta, sin theta)] , evaluate A cos theta + B sin theta .

If sqrt3 cos theta =sin theta , then the value of (4sin^2 theta -5 cos theta )/(3 cos theta +1) is: यदि sqrt3 cos theta =sin theta , तो (4sin^2 theta -5 cos theta )/(3 cos theta +1) का मान ज्ञात करें

Simplify, costheta[[cos theta, sin theta],[-sin theta, cos theta]] + sin theta [[sin theta, -cos theta],[cos theta, sin theta]]

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 f (theta) = [[cos^(2) theta , cos theta sin theta,-sin theta],[cos theta sin theta , sin^(2) theta , cos theta ],[sin theta ,-cos theta , 0]] ,then f ( pi / 7) is

If f (theta) = [[cos^(2) theta , cos theta sin theta,-sin theta],[cos theta sin theta , sin^(2) theta , cos theta ],[sin theta ,-cos theta , 0]] ,then f ( pi / 7) is

If f (theta) = [[cos^(2) theta , cos theta sin theta,-sin theta],[cos theta sin theta , sin^(2) theta , cos theta ],[sin theta ,-cos theta , 0]] ,then f ( pi / 7) is

If f (theta) = [[cos^(2) theta , cos theta sin theta,-sin theta],[cos theta sin theta , sin^(2) theta , cos theta ],[sin theta ,-cos theta , 0]] "then " f (pi/7) is
