Answer:

\sqrt{2}


Step-by-step explanation:

We plug in i into f(x) to get:

f(i)=1-i


<em>Here, i is the imaginary number i=\sqrt{-1}</em>

To get absolute value of an imaginary number, we use the following formula:

a+bi=\sqrt{a^2+b^2}


So absolute value of f(i) is:

|f(i)|=\sqrt{(1)^2+(1)^2} \\=\sqrt{1+1} \\=\sqrt{2}

Please help me out :)
arlik [135]

Answer:

\frac{\sqrt{17} }{7}

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sinx = \sqrt{1-cos^2x}

Note that (\frac{4\sqrt{2} }{7})² = \frac{32}{49}

sinΘ = \sqrt{1-(32/49)}

        = \sqrt{\frac{17}{49} } = \frac{\sqrt{17} }{7}
