2cos^(2)theta-5cos theta+2=0

If a is a root of 25cos^(2)theta+5cos theta-12=0;(pi)/(2)

If 2 cos^2 theta-5 cos theta+2=0 , 0^@ यदि 2 cos^2 theta-5 cos theta+2=0 है और 0^@< theta< 90^@ है, तो (Cosec theta+Cot theta) का मान ज्ञात करें |

Solve the general vlaue. 2cos ^(2) theta - 5 cos theta + 2 = 0

If 2cos^(2)theta + cos theta -1 =0 then theta =

If 4-2 sin^2 theta-5cos theta=0, 0^@ यदि 4-2 sin^2 theta-5cos theta=0, 0^@< theta<90^@ , तो cos theta+tan theta का मान ज्ञात करें:

If 4-2 sin^2 theta-5cos theta=0, 0^@ यदि 4-2 sin^2 theta-5cos theta=0, 0^@< theta<90^@ , तो cos theta-tan theta का मान ज्ञात करें:

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)/12)=

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)/(12))

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
