Question

Express in simplest form: sec 0 • cot 0 • sin 0

Answer 1

`\sec \theta.\cot \theta.\sin \theta`

Note that;

secθ = 1/cosθ cotθ= cosθ/sinθ

substitute into into the expression

`\sec \theta.\cot \theta.\sin \theta=(1)/(\cos\theta).(\cos \theta)/(\sin \theta)\text{. sin}\theta`

cosθ at the numerator will cancel out the cosθ at the denominator, also sinθ at the numerator will cancel out the sinθ at the denominator

`=1`
