If Tanø =a/b Find the value of sinø+cosø/sinø-cosø
inysia [295]

Answer:

\frac{b+a}{b-a}

Step-by-step explanation:

Tan θ = \frac{perpendicular}{base} = \frac{b}{a}

So, Perpendicular = b, base = a

<em><u>Finding hypotenuse by Pythagorean Theorem:</u></em>

c^2 = a^2+b^2

=> So, <u><em>hypotenuse = c</em></u>

Sin θ = \frac{perpendicular}{hypotenuse}= \frac{b}{c}

Cos θ = \frac{base}{hypotenuse}= \frac{a}{c}

So, <u><em>Now finding </em></u>\frac{sin\theta+cos\theta}{sin\theta-cos\theta}

=> \frac{b}{c} + \frac{a}{c} ÷ \frac{b}{c} - \frac{a}{c}

=> \frac{b+a}{c} ÷ \frac{b-a}{c}

=> \frac{b+a}{c} * \frac{c}{b-a}

=> \frac{b+a}{b-a}
