[1/1 Formula]
    Work: Calculate the value of equation 12*cos90-72*(cos(180))*(36*(cos90)^2+325)^(-1/2)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2 .
    Question type: Mathematical calculation
    Solution:
          12*cos90-72*(cos(180))*(36*(cos90)^2+325)^(-1/2)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(cos180)*(36*(cos90)^2+325)^(-1/2)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*(36*(cos90)^2+325)^(-1/2)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*(36*(-0.448074)^2+325)^(-1/2)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^(-1/2)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^(-0.5)-(36*(cos90)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^-0.5-(36*(-0.448074)^2+325)^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^-0.5-332.227731^(-3/2)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^-0.5-332.227731^(-1.5)*2592*(sin90)^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^-0.5-332.227731^-1.5*2592*0.893997^2*(cos90)^2
        =12*cos90-72*(-0.59846)*332.227731^-0.5-332.227731^-1.5*2592*0.893997^2*(-0.448074)^2
