Like so:
.
Here's my worked solution:
73% → 73/100
Use the following facts:
sin(a + b) = sin(a)cos(b) + sin(b)cos(a)
sin(a - b) = sin(a)cos(b) - sin(b)cos(a)
and set a = 0.5x, b = 0.1x
to show that sin(0.6x) - sin(0.4x) → 2sin(0.1x)cos(0.5x)
Pi is defined as the ratio of the circumference of a circle to its diameter.
Alternative hint: First multiply through by e-x then make the substituion z = ye-x
14!/(2!12!) → 14*13/2 → 7*13 → 91
If I've interpreted the question correctly, then, using L for length and W for width and height, we have:
