What is an EMG/NCS and why is it helpful? EMG stands for Electromyograghy and NCS stands for Nerve Conduction Study. These two studies are done together; but on occasions, the EMG portion is skipped depending on the diagnosis and the result of the NCS portion. The test is performed in the sitting or lying position.
Math Planet If : A conditional statement is false if hypothesis is true and the conclusion is false. If we rearrange a conditional statement or change parts of it then we have If both statements are true or if both statements are false then the converse is true.
The second important kind of geometric proof is indirect proof. In an indirect proof, instead of showing that the conclusion to be proved is true, you show that all of the alternatives are false. To do this, you must assume the negation of the statement to be proved. Then, deductive reasoning will lead to a contradiction: two statements that cannot both be true. A contradiction shows that the assumption made earlier is impossible, and therefore false. Thus, the statement to be proved must be true, because its negation is false. Below is a sample indirect geometric proof.
