Calculate `theta_(1)` and `theta_(2)` in shown situation.

Two particles of equal mass in are projected from the ground with speeds v_(1) and v_(2) at angles theta_(1) , and theta_(2) as shown in the figure. Given theta_(2)gttheta_(1) and v_(1)costheta_(1)=v_(2)costheta_(2) Which statement/s is/are correct?

If theta_(1) and theta_(2) are two solutions of the equation a cos2 theta+b sin2 theta=c then tan theta_(1)+tan theta_(2)

theta_(1),theta_(2)in[0,2pi]andtheta_(1) and theta_(2) satisfy the equation tantheta=1 then tan((theta_(1))/(2)).tan((theta_(2))/(2))= ………….

"The two different values of "theta," namely "theta_(1)" and " theta_(2) " satisfy " sin ( theta + phi) = 1/2 sin 2 phi , " prove that ," (sin theta_(1) + sin theta_(2))/(cos theta_(1) + cos theta_(2))=cot phi

If theta_(1), theta_(2) are solutions of the equation a cos 2theta + bsin 2theta = c, tan theta_(1) != tan theta_(2) and a+c != 0 , then find the values of (i) tan theta_(1) + tan theta_(2) (ii) tan theta_(1).tan theta_(2) .

If roots of equation 3x^(2)+5x+1=0are(sec theta_(1)-tan theta_(1))and(cos ec theta_(2)-cot theta_(2)) Then find the equation whose roots are (sec theta_(1)+tan theta_(1))and(cos e theta_(2)+cot theta_(2))

The values of sintheta_(1), cos^(2)theta_(2) and tan theta_(3) are given as .^(1)//_(2), -.^(1)//_(2) and 3 (not in order), for some angles theta_(1), theta_(2) and theta_(3) . Choose incorrect statement.A
