Find `(-270)-(-270)`

If A=[(x,3,2),(-2,y,-7),(-2,7,0)] and A=-A^(T) then x+y=

cos A + sin(270^(@) +A)-sin(270^(@)-A)+ cos(180^(@)-A)=

If sin(270^(@) - x) = cos 292^(@) , then find x in (0, 360^(@))

If sin(270^(@)-x)=cos292^(@) then the values of x lying between 0^(@) and 360^(@) are

If tan theta = -(5)/(12) and theta is not in the fourth quadrant then ( tan (90^(@)+ theta ) - sin(180^(@) - theta ))/( sin (270^(@)- theta ) + " cosec " (360^(@) - theta ))=

Calculate the standard internal change in multiples of -10^(2)KJ for the reaction OF_(2(g)) + H_(2)O_((g)) rarr O_(2(g)) + 2HF_((g)) at 298K. The standard enthalpies of formation of OF_(2(g)), H_(2)O_((g)), HF_((g)) " are " +20, -250 and -270KJ "mole"^(-1)

sin(270^@+theta)=

"cosec"(270^(@)-A)+"cosec"(90^(@)-A)+sec(90^(@)-A)+sec(270^(@)-A)=

Use Euclid's division algorithm to find the HCF of (i) 900 and 270
