If sin theetha +cos theetha =2 Cosec theetha + sec theetha =??? Share with your friends Share 1 Lovina Kansal answered this Dear student Given, sinθ+cosθ=2 ...(1)Squaring both sides, we getsinθ+cosθ2=22⇒sin2θ+cos2θ+2sinθ cosθ=4 ∵a+b2=a2+b2+2ab⇒1+2sinθ cosθ=4 ∵sin2A+cos2A=1⇒2sinθ cosθ=3⇒sinθ cosθ=32 ....(2)Consider,cosecθ+secθ=1sinθ+1cosθ=cosθ+sinθsinθ cosθ=232 using 1 and 2=43So, cosecθ+secθ=43 Regards -1 View Full Answer Vansh Ishan answered this Dear student, Sin A cos A = 2, Cosec A sec A =? Ans. Cosec A ? sec A = 1/sinA ?1/ cos A = 1/ Sin A Cos A = 1/2. (You can replace theeta by A). 1
