In a AABC, if C = 90°, r and R are the inradius and circumradius of the ABC respectively, then 2(r + R) is equal to
b + c
c + a
a + b
a + b + c
Let be two distinct roots of where a, b, c are three real constants and . Then, is also a root of the same equation, if
a + b = c
b + c = a
c + a = b
c = a
If are solutions of the differential equation
where a0, a1 and a2 are real constants, then which of the following is/are always true?
is a solution, where A and B are real constants
