If cosec θ = √10 then secθ = ? (a) 3/√10 (b) √10/3 (c) 1/√10 (d) 2/√10
HeArty:
it's B
cosec©=√10
yes it is B
we know that Sin©=1/cosec©..so sin©=1/√10.......i have a formula sin^2©+cos^2©=1...\\=>cos^2©=1-sin^2©......put the value of sin© in this eq.......we get.//// cos^2©=1-1/10/////cos^2©=9/10.../////cos©=3/√10.......//// By formula cos©=1/sec©\\\\\. sec©=√10/3
