Answer:cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
tan²(x) - sin²(x) = sin²(x)/cos²(x) - sin²(x)
… = sin²(x) (1/cos²(x) - 1)
… = sin²(x) (sec²(x) - 1)
… = sin²(x) tan²(x)
Step-by-step explanation:
Add Two-thirds to both sides
solution:
x-2/3= 5/6
We have to find how this can be solved for "x" in one step
Remember that,
We we add or subtract same number from both sides of a equation, the equation still remains true
Therefore, from given,
x-2/3=5/6
Add Two-thirds to both sides
x-2/3+2/3=5/6+2/3
x=5/6+2/3
x=9/6
Add Two-thirds to both sides to solve the sum
