Calculating R-value involves ASHRAE making measurements of heat flux over different insulation materials and determining the R-value of insulation based on how quickly (or slowly) this heat flows through the material.
1 f(x) = 3 cos x – 4 sin x. Given that f(x) = R cos (x + α), where R > 0 and 0 ≤ α ≤ 90, Find the value of R and the value of α. Hence solve, for 0 ≤ θ ≤ 360, the equation. 3 cos x – 4 sin x = 1. Give your answers to 1 decimal place. Write down the minimum value of 3 cos x – 4 sin x.
The most common way to calculate the correlation coefficient (r) is by using technology, but using the formula can help us understand how r measures the direction and strength of the linear association between two quantitative variables.
