Solution

sin 45° + cos 45° + tan 45° = `1/sqrt(2) + 1/sqrt(2) + 1`

= `(1 + 1)/sqrt(2) + 1`

= `2/sqrt(2) + 1`

= `sqrt(2) + 1`

Hence, the value of sin 45° + cos 45° + tan 45° is `sqrt(2) + 1`.

Prove that: cot θ + tan θ = cosec θ·sec θ

Proof: L.H.S. = cot θ + tan θ

= `square/square + square/square`  ......`[∵ cot θ = square/square, tan θ = square/square]`

= `(square + square)/(square xx square)`  .....`[∵ square + square = 1]`

= `1/(square xx square)`

= `1/square xx 1/square`

= cosec θ·sec θ  ......`[∵ "cosec"  θ = 1/square, sec θ = 1/square]`

= R.H.S.

∴ L.H.S. = R.H.S.

∴ cot θ + tan θ = cosec·sec θ
