If tan theta= 3/4 , find csc theta
dangina [55]

Answer:

csc\theta=\frac{5}{3}

Step-by-step explanation:

Given:

tan\theta =\frac{3}{4}

cot\theta =\frac{4}{3}                 [∵ cot\theta =\frac{1}{tan\theta} ]

Squaring both sides.

cot^2\theta =\frac{4^2}{3^2}=\frac{16}{9}

csc^2\theta -1=\frac{16}{9}        [∵ cot^2\theta =csc^2\theta-1] ]

Adding 1 to both sides.

csc^2\theta -1+1=\frac{16}{9}+1

csc^2\theta =\frac{16}{9}+1

csc^2\theta=\frac{16}{9} +\frac{9}{9}     [Taking LCD=9 and adding fractions ]

csc^2\theta=\frac{16+9}{9}

csc^2\theta=\frac{25}{9}

Taking square root both sides.

\sqrt{csc^2\theta}=\sqrt{\frac{25}{9}}

∴ csc\theta=\frac{5}{3}
