Using the online linear regression calculator ; the regression model obtained is :

ŷ = 0.00345X + 1.00301

0.00345 = slope or gradient

1.00301 = intercept ; where the regression line crosses the y axis

X = independent variable or predictor variable ; y = dependent variable or predicted variable

Simplify this expression: cos theta/ tan theta cot theta

Dmitry_Shevchenko [17]

Q: $\frac{cos\theta}{tan\theta.cot\theta}=?$

A:

$\frac{cos\theta}{tan\theta.cot\theta}=cos\theta$

because... $tan\theta.cot\theta=1$
*********************************************************
Q: $\frac{cos\theta}{tan\theta}.cot\theta=?$

A:

$\frac{cos\theta}{tan\theta}.cot\theta&= \\ \\ \frac{cos\theta}{\frac{sin\theta}{cos\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^2\theta}{sin\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^3\theta}{sin^2\theta}}&= cos^3\theta.cosec^2\theta$
