Question

x cos A - y sin A = 0
x sin A+ y cos A= 0
find value of x and y​

Answer 1

Answer:

x=0,y=0

Step-by-step explanation:

by elimination method,

xcosA-ysinA=0×sinA

xsinA+ycosA=0×cosA

..........................................

xcosAsinA=ysin^2A

xsinAcosA=-ycos^2A

..-....................-..................

y(sin^2A+cos^2A)=0

y=0

so, xcosA=0(sinA)

x=0
