PROVE THAT TAN90 INFINITY

Asked by IOUHIU OYYFGY | 26th Nov, 2010, 06:25: PM

Expert Answer:

Dear student,
 
tan90 is not infinity.
 
sin90 = 1 and cos90 = 0
so tan 90 = 1/0 and division by zero is not defined,
so tan 90 is not defined.
 
Also note that infinity is not a value , it is a symbol.
 
we hope this clarifies your query,
