Cot(5pi/12) = tan(pi/12)
tan(x/2) = (1 - cos(x)) / sin(x))
tan(pi/12) = tan((pi/6)/2) = (1 - cos(pi/6)) / sin(pi/6))
sin(pi/6) = 1/2
cos(pi/6) = sqrt(3) / 2
so...
tan(pi/12) = (1 - sqrt(3)/2) / (1/2) = 2 - sqrt(3)
"-5 - 4i" is the one expression among the following choices given in the question that is the <span>conjugate of a complex number with -5 as the real part and 4i as the imaginary part. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope it helps you.</span>
The first one is the second one is All real numbers Step- by-step explanation:
1. Anything raised to the " zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.
Answer:
1.2 should be right but no promises
The first one because for every output there is only 1 input
