Using sum and difference identities from trigonometric identities shows that; Asin(ωt)cos(φ) +Acos(ωt)sin(φ) = Asin(ωt + φ)
How to prove Trigonometric Identities?We know from sum and difference identities that;
sin (α + β) = sin(α)cos(β) + cos(α)sin(β)
sin (α - β) = sin(α)cos(β) - cos(α)sin(β)
c₂ = Acos(φ)
c₁ = Asin(φ)
The Pythagorean identity can be invoked to simplify the sum of squares:
c₁² + c₂² =
(Asin(φ))² + (Acos(φ))²
= A²(sin(φ)² +cos(φ)²)
= A² * 1
= A²
Using common factor as shown in the trigonometric identity above for Asin(ωt)cos(φ) +Acos(ωt)sin(φ) gives us; Asin(ωt + φ)
Complete Question is;
y(t) = distance of weight from equilibrium position
ω = Angular Frequency (measured in radians per second)
A = Amplitude
φ = Phase shift
c₂ = Acos(φ)
c₁ = Asin(φ)
Use the information above and the trigonometric identities to prove that
Asin(ωt + φ) = Asin(ωt)cos(φ) +Acos(ωt)sin(φ)

When a value is 68% likely to occur, then it is 1 standard deviation from the mean. If data is incredibly rare, then it will be 0 standard deviations from the mean.
What is the empirical rule?This is a rule that predicts the percentage of values the further you go from the mean. 1 standard deviation from the mean would have 68% of the values.
The further you go from the mean, the higher the percentage of values that will be seen such that 3 standard deviations from the mean has 99% of values.
A 0 standard deviation from the mean is incredibly rare and points to identical values which isn't realistic and is why such discoveries would be considered new.

A programmer intended to compute (a AND b) OR c, and wrote the following code, which sometimes yields incorrect output. Why
A programmer intended to compute (a AND b) OR c, and wrote the following code, which sometimes yields incorrect output. The reason for this is because:
AND and OR are logical operators that operate on Boolean expressions to return true or false results.However, | and & are bitwise operators that act on a given number's binary digits bit by bit and yield a new number after the operation.Who is a computer programmer?A computer programmer is a person who specializes in creating codes with which a computer is instructed to achieve a specific and expected output.
What are the other reasons for the inconsistent yield or output?The program attempts to calculate (a AND b) OR c using the logical operators AND and OR, which will return either 1 (True) or 0 (False) depending on the inputs.
However, in the program, the programmer used the bitwise or(|) and bitwise and(&) operators: c | (a & b), which returns a new number depending on the values of a, b, and c.
As a result, it will produce the right outcome only when the logical AND - OR operation and bitwise and - or on inputs a, b, and c produce either 0 or 1. Otherwise, the outcome will be inaccurate.
As a result, the right response is that bitwise operators should be substituted by logical operators.
