Find the exact values of cos 3 pi/4 radians sin 3 pi/4 radians.

Liula [17]

If you consult the unit circle, you will see that:

$cos(\frac{3\pi}{4}) = -\frac{\sqrt{2}}{2}\\\\sin(\frac{3\pi}{4}) = \frac{\sqrt{2}}{2}$

3pi/4 in degrees is 3pi/4 * 180/pi = 3/4 * 180 = 135 degrees. And please refer to the attachment to how you can obtain the values above.

Now, lets multiply it together.

$-\frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2} =\\\\-\frac{2}{4} =\\\\ \boxed{\bf{-\frac{1}{2}}}$

So, <span>cos(3pi/4)sin(3pi/4) = -1/2</span>

How can you express 499 to find the product 499 x 5 using mental math? explain

Mashcka [7]

We can write 499 as 499 = 500 - 1

Because it is easy to multiply 500 and 5 compare to 499 to 5.

So product of 499 * 5 = (500 - 1)*5
= 500*5 - 1*5
= 2500 -5 = 2495

So the answer is 2495.

Ivan evaluated the expression 8+12÷3×2 and got 10. What mistake did he make?

lesya [120]

Ivan forgot to follow PEMDAS
Division first
12/3 = 4
4 x 2 = 8
8 + 8 = 16
Hope this helps!
