Question

If sin0-cos0=0 then find the value of sin40+cos40

Answer 1

Answer:

$\frac{8 \ }{ \sqrt{2} }$

is the correct answer

Answer 2

Hola mate here is your answer:

Solution:

Sin theta-cos theta=0

Sin theta=Cos theta=45°

Sin ^4 theta + cos^ 4 theta

$\frac{1}{ {( \sqrt{2} )}^{4} } + \frac{1}{ {( \sqrt{2}) }^{4} }$

$\frac{1}{4} + \frac{1}{4}$

$= \frac{1}{2}$
