" (iii) "(a sin alpha,-b cos alpha)" and "(-a cos alpha,b sin alpha)

Find the distance between the following pair of points: (a sin alpha,-b cos alpha) and (-a cos alpha,b sin alpha)( ii) (a,0) and (0,b)

Find distance between the pair of points given. (i) (a sin alpha, - b cos alpha) , ( - a cos alpha , b sin alpha ) (ii) ( a + b, b + c) , (a - b , c - b) (iii) ( 4, 10) , (7 - 6 )

If x=a sin alpha+b cos alpha and y=a cos alpha-b sin alpha then remove alpha

|(sin alpha, cos alpha),(cos alpha, -sin alpha)|=

IF tan alpha = ( sin alpha - cos alpha )/( sin alpha + cos alpha) , then sin alpha + cos alpha is

Find the value of f(alpha, beta) =|(cos (alpha + beta), -sin (alpha + beta), cos 2beta),(sin alpha, cos alpha, sin beta),(-cos alpha, sin alpha, cos beta)|

|(cos alpha, sin alpha, cos (alpha+beta)),(- sin alpha, cos alpha, -sin (alpha + beta)),(1,1,1)|=

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

tan theta = (sin alpha-cos alpha) / (sin alpha + cos alpha)
