So let me write it right over here. So we have our r squared, which is the percent of the total variation that is explained by x, is going to be 1 the minus that 0.12 that we just calculated. Which is going to be 0.88.
WebThe first shows how we can express sin θ in terms of cos θ; the second shows how we can express cos θ in terms of sin θ. Note: sin 2 θ-- "sine squared theta" -- means (sin θ) 2. … Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out.
