Sina+cosb=1/√2 & cosa+sinb=√2/√3 then find the value of : (1) sin(a+b) (2) tan(a-b/2)
Sina+cosb=1/√2 Sina = 1/√2 – cosb squaring both sides, (sina)^2 = 1/2 + (cosb)^2 – 2cosb/ √2 1 – (cosa)^2 = 1/2 + (cosb)^2 – 2cosb/ √2 1/2 – (cosa)^2 = (cosb)^2 – 2cosb/...

If 2a+b+2c=0, then the family of lines ax+by+c=0 is concurrent at
Make ax+by+c=0 similar to 2a + b + 2c = 0 therfore multiply ax+by+c=0 by 2 .i.e. 2ax + 2by + 2c = 0 Now compare it with the coeff. of 2a+b+2c=0 we get, x = 1 y = ½ thus at this point it is...
