Question
जर tanθ = 1 तर `(sinθ + cosθ)/(secθ + "cosec"θ)` ची किंमत काढण्यासाठी खालील कृती पूर्ण करा.
कृती:
tan θ = 1 ..[दिलेले]
परंतु tan `square` = 1
∴ θ = `square`
∴ `(sin θ + cos θ)/(sec θ + "cosec" θ) = (sin 45^circ + cos 45^circ)/(sec 45^circ + "cosec" 45^circ)`
= `(1/square + 1/sqrt(2))/(sqrt(2) + square)`
= `(2/sqrt(2))/square`
`(sin θ + cos θ)/(sec θ + "cosec" θ) = 1/square`

Solution
tan θ = 1 ..[दिलेले]
परंतु tan \[\boxed{45°}\] = 1
∴ θ = \[\boxed{45°}\]
∴ `(sin θ + cos θ)/(sec θ + "cosec" θ) = (sin 45^circ + cos 45^circ)/(sec 45^circ + "cosec" 45^circ)`
= \[\frac{\frac{1}{\boxed{\sqrt2}} + \frac{1}{\sqrt2}}{\sqrt2 + \boxed{\sqrt2}}\]
= \[\frac{\frac{2}{\sqrt2}}{{\boxed{2\sqrt2}}}\]
`(sin θ + cos θ)/(sec θ + "cosec" θ)` = \[\frac{1}{\boxed{2}}\]
