trig

im lost on part B, my first assumption was 6.5 as cos theta = 0 but that just gives a value of t outside the range when you solve it, or maybe im solving it wrong im not sure

the equation is 6.5 + root10(cos(pi * t/13 - 4.322)) btw

i think

[hollow matrix]

set that equal to -1

so it would be 6-root10

for ii solve (cos(pi * t/13 - 4.322)) =-1

ohhh shit

that would be the minimum yeah

thanks
