bitch ass Physics problem
Half the weight and divide by sin(10)
Solution to this?
Find the min, max of A = 5sinX - 12cosX
My solutions
- Input f(x) = 5*sin(x) - 12*cos(x) in the calculator and get -13 and +13 in the plotting
- Find an y for which 5/y and 12/y are valid cos, sin of the same angle. For that, we need (5/y)^2 + (12/y)^2 = 1, and y=13; Now we can transform the expression to 13*(5/13 * cosX - 12/13 * sinX), where 5/13 and 12/13 are sin(z) and cos(z), and that becomes 13*sin(X-Z), and the min, max of sin are -1 and 1, so the answer is -13, 13
Anything simpler?
Differentiate the function, set the gradient equal to zero. That’ll tell you the location of the turning points, then just see what values they give as arguments for f(x) and identify whether they’re maximum or minimum :)

Wow. Just for the fact that these McFlurry’s are like 2x the size of the ones in the UK make me sad… (it’s not like I buy them anyway as I’d rather not have to SHOUT TO DUMB SHITS FROM MY SCHOOL)
do you actually think there is a mcflurry the size of samuel l jackson’s head
YEAH. FOR SEVEN FUCKING YEARS, YOU UNGRATEFUL LITTLE SHIT.

Was there a more romantic scene shot that didn’t involve a roundhouse kick?
I like to hope that all of the meaningless objects and stories people surround themselves with are just a mask… a mask to hide us from a deep-rooted despair and anguish and panic we are all feeling together.
I like to hope people are as terrified and lonely as I am.
