Find sin (a) given that cos (a)=1

Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.

a=2πn, for any integer n

total of apples - take away four

6-4 = 2

answer is 2 apples

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
