• You can put this solution on YOUR website! tan(x)sec(x)-2tan(x)=0 Solving these equations usually starts with using algebra and/or Trig. identities to transform the equation so that you have one or more equations of the form:
• Solve each equation for all values of x in the real number system. If an exact solution does not exist, round your answers to the nearest hundredth.
• keywords: of,real,sup,Solve,radic,cos,values,for,sin,all,Solve 4 sin² x+4√(2) cos x -6 = 0 for all real values of x Related Rewrite the equation y =(x/5) + 6 in standard form..
• For example, given the equationx – 1| > –5, x is all real numbers. The left-hand side of this equation is an absolute value, and an absolute value always represents a positive number (or zero). Because positive numbers (or zero) are always greater than negative numbers, these types of inequalities always have a solution. Any real number that you put into this equation works.
